I moved the following sentence from the main article here:
I am not sure this is correct. First of all, hemoglobin is red whether it contains oxygen or not. Second, if it contains oxygen, then it contains molecular oxygen (O2) and not oxydized iron. Could somebody with a firmer grasp on these things please confirm? -- AxelBoldt
Yeah I think this is correct. Oxygen is bound to the Haem groups in haemoglobin chains to form oxyhaemoglobin (HbO8:
Hb + 4O2 -> HbO8
Although 'oxidized' may not be so chemically correct (I don't know about loss of electrons) they are loosely bound and not in the 02 form.
The forst photograph to illustrate RED is poor. It is not red. It may rlink to red in people's minds; but red it is not. If you want a red photo, I will find. —Preceding unsigned comment added by 86.151.232.119 ( talk) 21:34, 2 December 2007 (UTC)
Do you think the original statement, claiming that blood is red because of oxidized iron, is correct, or that my statement above is correct? -- AxelBoldt original statemen -- sodium
Well, I don't understand your argument. What are you claiming actually causes the red colour of haemoglobin? As far as I know, haematite is red because of the Fe3+ ions. Haemoglobin (both oxy- and deoxy-) has Fe2+ ions - the iron is not oxidized by the binding of oxygen. Fe2+ ions cause a yellow-green colour, I think, so they can't be what makes haemoglobin red. Unless I've got something wrong here, the original statement is at best very misleading. -- Zundark, 2001 Oct 8
The color of an ion depends on its environment. In aqueous solution ferric irons (Fe3+) are coordinated with six water molecules and have a yellow color rather than the reddish color of hematite, where they are coordinated with six oxide ions, while the anhydrous chloride is greenish. Fe2+ are green in aqueous solution but that doesn't say much, the presence of nitrogen and oxygen (only oxyhemoglobin is bright red) are going to affect the color significantly. The iron is definitely what is responsible, though, and most brightly colored compounds are made so by coordinated transition metals. Someday we should have an article on ligand field theory.
How about the following statement:
That avoids the term "oxidization" which is not involved in hemoglobin if I understand it correctly. -- AxelBoldt
Have some questions about this statement
In most if not all human languages, "red" is the first color name developed after "black" and "white."
I'm not sure what this means. Does it mean that ten thousand years ago, people only talked about black and white and then someone invented the word red? Or does it mean that babies learn to identify red after they identify black and white.
It's not obvious to me that we know enough about the development of language to make the first statement. If the second is true they it should be expanded.
Although it's true that red is traditionally the color used on maps for the U.S. Republican party, it seems inconsistent to say this when the maps featured on Wikipedia use red for Democrats. Media:Image:ElectoralCollege2000.png I'm not sure how/if I should add this to the article, though, so I'm just tossing it out there. Rebrane
"The RGB coordinates of red are 255 0 0. Note that the red phosphor on CRT-based computer displays is slightly yellowish compared to a "peak" pure spectral red color: see metamerism."
True or false: the "peak" pure spectral red color is 255 0 128??
A discussion of metamerism wrt. CMYK might have been interesting, but it is not relevant to the RGB colorspace, since RGB is used for light sources themselves. Since I'd put in a nicer colorspace block, we can delete the paragraph entirely. Kim Bruning 21:15, 3 Apr 2004 (UTC)

This page says, "Red light has a wavelength range of roughly 630-760 nm." However, if you follow the link from "630-760" that other page says "625-740 nm — wavelength of red light".

Is it notable enough to mention that red is sometimes the prefered hair colour for the leader of a team in animated series, and therefore connected to leadership?

Red is not used in the Roman Catholic Church on Holy Thursday. Red is used for the Holy Spirit, the martyrs, and Jesus' Passion. Holy Thursday celebrates none of these, but rather the institution of the Holy Eucharist, for which white vestments are worn.

The CMYK details in the infobox are displayed in the article as "0, 100, 0, 0" (magenta), though the source correctly indicates 100 for yellow. Strange. Or is it just me?-- Jeffro77 10:30, 30 October 2006 (UTC)
Are these things really necessary in the color infoboxes? Are they accurate enough? Sure, while #FF0000 might be red, so is #AA0000,and even #110000, just not as bright(meaning not as many photons of that wavelength are being emitted). It is still red regardless. I'm not really for deleting things, but is there a good reason for having this? This is an article for the color "Red", I don't see why the computer application of colors seem to take a sort of dominance in them. Wikidan829 16:17, 8 May 2007 (UTC)

Though AFAIK the term "reddening" can also refer to the pagan practice of bleeding on objects to color them in a belief that doing so imbues them with power, energy and lifeforce... For example, in Nordic & Germanic paganism, "reddening the runes" is coloring their carved alphabetic characters used for writing with the blood of the writer. Maybe there should be a disambiguation page for this other usage of 'reddening' meaning to bleed unto as commonly used, particularly in Germanic mythology and ancient practice rather than simply a redirect to the 'red' article. 4.242.192.96 ( talk) 04:07, 6 January 2009 (UTC)

I've have a quick read through and this is a very interesting article. It will probably make GA this time round, but some work will be needed in at least a couple of sections. The Pigments section is merely a tabulated list of wikilinks and is devoid of text. I would have expected some discussion (its not going to make GA as it is) of pigments, possibly starting with natural (mineral and animal based) pigments and then going on to synthetic (oil-based) pigments; possibly paints, varnishes, stains, etc - but I will cover that in more detail later. I think that the photographic section (well one paragraph) is rather thin - but I will also cover that in more detail latter.
I will now be starting a detailed review, section by section, but leaving the WP:Lead until last.
To clarify my points above, this article is quite close to being a GA so I'm not going to quick fail it; but I'm not accepting Pigments, for instance in its current state. This review is likely to take at least a day or so. Pyrotec ( talk) 20:09, 14 April 2010 (UTC)

What RGB coordinates do you think sound more natural to call "pure red"?? The reason most people like to say 255 0 0 is because of the R that stands for red. However, 255 0 128 is actually pure red, defining it as red that is totally neutral on the blue-yellow scale (the scale that defines blue and yellow.) Practice this:
Go to Microsoft PowerPoint. Upon seeing the first slide, edit the colors so that the background has RGB coordinates of 255 0 128. Then, draw a rectangle or oval and make the coordinates 255 0 0. Then, set the line settings for the rectangle and oval so that there is no line. You will see that the rectangle or oval is actually somewhat orange-ish and that the background is more pure red.
There is another version of this, which is to replace "red" with " green", "255 0" as the first 2 RGB coordinates with "0 255", and "orange-ish" with "lime-ish".
"This is the only color word which has been traced to an Indo-European root."?
Blue has this: "Through a Proto-Indo-European root, it is also linked with Latin flavus ("yellow"; see flavescent and flavine), with Greek phalos (white), French blanc (white, blank) (borrowed from Old Frankish), and with Russian белый, belyi ("white," see beluga)"...
The ref, in the online etymology dictionary is to "The only color for which a definite common PIE root word has been found."
The same dictionary gives for blue: "PIE *bhle-was 'light-colored, blue, blond, yellow.'"
I'm going to take that sentence out.-- Annielogue ( talk) 23:42, 22 April 2010 (UTC)
However, the major exception is the United States. There, red is associated with the right-wing Republican Party. (The reason is that U.S. television networks assigned blue and red to states awarded to the Republicans and the Democrats, respectively, on news maps; the color assignments were alternated every presidential election, but the controversial 2000 presidential election was when commentators happened to pick up on the color choices.)
What does this mean?

One of the interesting idiosyncracies of Old English is that the word "red" is frequently used to describe the metal gold.

Why is red used for the stop signal at traffic lights, etc.? Tabletop ( talk) 15:28, 25 July 2013 (UTC)
Wouldn't it be more appropriate and technically correct to begin this article with "Red is the color of the wavelength of light from approximately 620–740 nm on the electromagnetic spectrum. Next to orange at the end of the visible spectrum, red is the color of blood, rubies, and strawberries, and is commonly associated with danger, sacrifice, passion, fire, beauty, blood, anger, Christmas, socialism, communism, and in China and many other cultures, with happiness." (fns omitted).
Specifically, the edits would be:
Red is the color [begin strike] of blood, rubies and strawberries.[3][4] It is the color [end strike] of the wavelength of light from approximately 620–740 nm on the electromagnetic spectrum.[2] Next to orange at the end of the visible spectrum, red is [insert] the color of blood, rubies, and strawberries, and is [end insert] commonly associated with danger, sacrifice, passion, fire, beauty, blood, anger, Christmas, socialism, communism, and in China and many other cultures, with happiness.[5]
I understand your point of view, but I'm afraid I don't agree. The wavelength of red isn't the main subject of the article; it's mentioned only once in the section on optics. The main subjects of the article are the common uses, appearances in nature, associations and history of the color. The opening citing blood, rubies and strawberries is the description used in the Oxford English Dictionary, and other dictionaries, and I think it's what most people think of when they think of red. Given this, I think that a good lead for this article should reflect the majority of the content of the article and not put so much emphasis on the wavelength. Red is a lot more than just a wavelength of light. SiefkinDR ( talk) 18:53, 27 April 2014 (UTC)

Please remove 'fire' from the first sentence of the article, as it is not agreed upon that red is the colour of fire. Flames come in many colours depending on temperature and fuel, and it is certainly debatable that even a common wood fire (which the sentence is likely referring to) is red, as opposed to orange, yellow, or a mixture of colours. 2601:B:AF80:6E9:39D1:B456:381E:12DC ( talk) 08:56, 19 February 2015 (UTC)
I don't think anyone who's read the intro sentence will have failed to scratch their heads at the seeming arbitrariness of the examples used. It seems that the entry on Yellow follows a similar form, but it cites this form as being taken from the Webster's New World Dictionary of 1964. Merriam-Webster Online too has as its primary definition "having the colour of blood," but the justification for this definition seems like it rests on certain etymological associations between the name of the colour and its originally signifying "bloodlikeness" in some languages. Anyhow all I mean to say is that I believe it would make more sense to address what it is in scientific terms before getting on to cultural and etymological significance etc. — Preceding unsigned comment added by Knock-kneed ( talk • contribs) 00:14, 18 February 2015 (UTC)
Acording to the CIE standard observer the human visual system can detect light a wavelengths up to 830 nanometers, which will be perceived as red. The sensetivity is not high, only 1/1000 of the max so it is normally ignored. However it should not, I think, be ignored in the science section. Thorseth ( talk) 20:18, 5 April 2015 (UTC)

According to the Wikipedia Manual of Style, the first paragraph of the lead should explain briefly why the subject is notable. Red is certainly not notable only because of its wavelength, but because it has an important place in nature, history, culture and symbolism. Red as the color of blood, rubies and strawberries are all discussed, explained and illustrated in the article below. SiefkinDR ( talk) 12:34, 10 October 2017 (UTC)
The lead now has twenty-four lines devoted to optics and science and just four lines devoted to the rest of the article. This doesn't work at all. SiefkinDR ( talk) 13:08, 15 October 2017 (UTC)
The lead sentence has to establish the importance of the color in history, culture and nature. Just giving the wavelength doesn't do that. It needs some examples in the first sentence to do that. SiefkinDR ( talk) 09:41, 17 October 2017 (UTC)
There are a surprising number of different variations of wavelength given for red light in Wikipedia, depending upon which article you look at.
There's also a lot of variation in other sources outside Wikipedia.
Do we know that the number in this article is more accurate than other sources? SiefkinDR ( talk) 19:40, 19 October 2017 (UTC)
I propose that we take out the approximate wavelength from the definition in lead paragraph, and simply give the place in the spectrum. As the citation says, it's not an accurate definition; it's just an approximation, it varies because of different conditions, and as the citation itself says, "most colored objects give off a range of wavelengths and the characterization of color is much more than the statement of wavelength." Comments? SiefkinDR ( talk) 07:31, 21 October 2017 (UTC)
Also, this is not the wavelength of scarlet, or the other varieties included in the article, since they're mixtures of different wavelengths of light. Better just to say where it lies on the spectrum, which is correct. Cordially, SiefkinDR ( talk) 09:26, 21 October 2017 (UTC)
Almost all reds are a combination of the wavelength of red with wavelengths of other colors, so I've added "dominant wavelength" to the lead, and a link defining it. I have also added a line to the lead noting the range of reds, including some prominent examples like crimson and scarlet, which are described and illustrated in the article.

A car is a four-wheeled vehiclemight skip having a cite because, in fact, a few cars have 3 or 6 wheels; the statement in the lead is giving a good general impression definition without getting bogged down into technical details that would defeat the purpose of the lede (as long as the details, like the other-wheeled cars, are fully and explicitly noted and cited elsewhere). From what I see on this Talk, the lede has some issues as already noted. Those issues should be sorted out before getting into cites for the parts of the lede under discussion. (On the wavelength, I think it's fine the lede has this, stated as "approximately", without needing a cite, if in the next section or two all the details of wavelength are fully stated and cited. After all, the equivalent info is in the infobox anyway. Just my opinion, of course.)

change colour to color Hesheweit ( talk) 19:23, 22 March 2018 (UTC)
Hello! There is a mistake in the introduction: "It is a primary color in the RGB color model and the CMYK color model, and is the complementary color of cyan." Red is complementary to cyan in RGB, and in CMYK mode it is opposite to Green. Let's teach correctly! Thanks.

The citation is already used on the

Currently I am checking all of the citations in this article. I am remaking all simple <ref> citations into their scripted counterparts. At the same time I try to add more relevant info if it is not already there. If needed, I also add archived versions. All of the information that is correct will stay as it was, including the date that the citation was added.
The biggest change I am going to do within citations is grouping all of the citations corresponding to Bibliography into single citation entries. That way it is possible to significantly reduce the number of citations. The page number that the citation is referring to in that sentence / paragraph is going to be displayed using the rp template. I would suggest other contributors to try using this template instead of creating multiple citations regarding the same work.
As for the Bibliography itself, even though it is going to be a duplicate of the citation entries, I think it should stay as it is. It is a shorter list of the most important works that this article was based on.

In section 6 "In Religion" or section 14 "Superstition" there should be a section about Paganism and/or Wicca. A bulletin could be placed stating "In modern Pagan and Wiccan religions, red is representative of the Root Chakra, the Chakra that grounds us to the world. It also is representative of energy, passion and courage. It is believed that when we don't have enough red in our lives we become fearful and lazy, and when we have too much we become angry, agitated and demanding" [1] Gagehannan ( talk) 00:42, 16 December 2019 (UTC) Gagehannan ( talk) 00:42, 16 December 2019 (UTC)
First, colors don't have history, so that article really should be History of red in human culture or such. The topic is interesting, but I am unsure it warrants a stand-alone article, and I think readers will be best served if this is integrated here. Also, this article talks about this topic in many sections, to WP:POVFORK is also an issue. Really, the difference is that the new article presents a chronological overview, while the old one here provides an overview by topic.

Red is one of the most favorite colors in the world. Judging that it has a bright opacity which attracts people
The explanation of the effects of Dichromacy is incorrect.
Red objects won't appear grey to a dichromat but rather a dark yellow depending on the distance to the absorption maximum of the yellow cones. Light with wavelengths greater than the absorption maximum of the yellow cones (i.e. light that appears orange or red to humans) will still appear yellow to a dichromat but darker because of the reduced absorption in this region. Sufficiently long wavelengths will have no absorption and thus look black. The human analoge is red objects that emit wavelengths greater than the absorption maximum of the red cones of humans. These wavelengths appear dark red or black to humans but not grey.
It is however true that green objects will appear grey to a dichromat because the green wavelengths fall in the area between the absorption maxima of the yellow and blue cones which are the complementary colors of a dichromat (with blue-yellow vision). Since a dichromat can distinguish only two colors, a mixture of light of these colors will appear white, grey or even black depending depending on the overlap of the absorption spectra of the blue and yellow cones respectively.

I moved the following sentence from the main article here:
I am not sure this is correct. First of all, hemoglobin is red whether it contains oxygen or not. Second, if it contains oxygen, then it contains molecular oxygen (O2) and not oxydized iron. Could somebody with a firmer grasp on these things please confirm? -- AxelBoldt
Yeah I think this is correct. Oxygen is bound to the Haem groups in haemoglobin chains to form oxyhaemoglobin (HbO8:
Hb + 4O2 -> HbO8
Although 'oxidized' may not be so chemically correct (I don't know about loss of electrons) they are loosely bound and not in the 02 form.
The forst photograph to illustrate RED is poor. It is not red. It may rlink to red in people's minds; but red it is not. If you want a red photo, I will find. —Preceding unsigned comment added by 86.151.232.119 ( talk) 21:34, 2 December 2007 (UTC)
Do you think the original statement, claiming that blood is red because of oxidized iron, is correct, or that my statement above is correct? -- AxelBoldt original statemen -- sodium
Well, I don't understand your argument. What are you claiming actually causes the red colour of haemoglobin? As far as I know, haematite is red because of the Fe3+ ions. Haemoglobin (both oxy- and deoxy-) has Fe2+ ions - the iron is not oxidized by the binding of oxygen. Fe2+ ions cause a yellow-green colour, I think, so they can't be what makes haemoglobin red. Unless I've got something wrong here, the original statement is at best very misleading. -- Zundark, 2001 Oct 8
The color of an ion depends on its environment. In aqueous solution ferric irons (Fe3+) are coordinated with six water molecules and have a yellow color rather than the reddish color of hematite, where they are coordinated with six oxide ions, while the anhydrous chloride is greenish. Fe2+ are green in aqueous solution but that doesn't say much, the presence of nitrogen and oxygen (only oxyhemoglobin is bright red) are going to affect the color significantly. The iron is definitely what is responsible, though, and most brightly colored compounds are made so by coordinated transition metals. Someday we should have an article on ligand field theory.
How about the following statement:
That avoids the term "oxidization" which is not involved in hemoglobin if I understand it correctly. -- AxelBoldt
Have some questions about this statement
In most if not all human languages, "red" is the first color name developed after "black" and "white."
I'm not sure what this means. Does it mean that ten thousand years ago, people only talked about black and white and then someone invented the word red? Or does it mean that babies learn to identify red after they identify black and white.
It's not obvious to me that we know enough about the development of language to make the first statement. If the second is true they it should be expanded.
Although it's true that red is traditionally the color used on maps for the U.S. Republican party, it seems inconsistent to say this when the maps featured on Wikipedia use red for Democrats.

"The RGB coordinates of red are 255 0 0. Note that the red phosphor on CRT-based computer displays is slightly yellowish compared to a "peak" pure spectral red color: see metamerism."
True or false: the "peak" pure spectral red color is 255 0 128??
A discussion of metamerism wrt. CMYK might have been interesting, but it is not relevant to the RGB colorspace, since RGB is used for light sources themselves. Since I'd put in a nicer colorspace block, we can delete the paragraph entirely. Kim Bruning 21:15, 3 Apr 2004 (UTC)

Are these things really necessary in the color infoboxes? Are they accurate enough? Sure, while #FF0000 might be red, so is #AA0000,and even #110000, just not as bright(meaning not as many photons of that wavelength are being emitted). It is still red regardless.

Though AFAIK the term "reddening" can also refer to the pagan practice of bleeding on objects to color them in a belief that doing so imbues them with power, energy and lifeforce... For example, in Nordic & Germanic paganism, "reddening the runes" is coloring their carved alphabetic characters used for writing with the blood of the writer.

I've have a quick read through and this is a very interesting article. It will probably make GA this time round, but some work will be needed in at least a couple of sections. The Pigments section is merely a tabulated list of wikilinks and is devoid of text. I would have expected some discussion (its not going to make GA as it is) of pigments, possibly starting with natural (mineral and animal based) pigments and then going on to synthetic (oil-based) pigments; possibly paints, varnishes, stains, etc - but I will cover that in more detail later. I think that the photographic section (well one paragraph) is rather thin - but I will also cover that in more detail latter.
I will now be starting a detailed review, section by section, but leaving the WP:Lead until last.
To clarify my points above, this article is quite close to being a GA so I'm not going to quick fail it; but I'm not accepting Pigments, for instance in its current state. This review is likely to take at least a day or so. Pyrotec ( talk) 20:09, 14 April 2010 (UTC)

What RGB coordinates do you think sound more natural to call "pure red"?? The reason most people like to say 255 0 0 is because of the R that stands for red. However, 255 0 128 is actually pure red, defining it as red that is totally neutral on the blue-yellow scale (the scale that defines blue and yellow.) Practice this:
Go to Microsoft PowerPoint. Upon seeing the first slide, edit the colors so that the background has RGB coordinates of 255 0 128. Then, draw a rectangle or oval and make the coordinates 255 0 0. Then, set the line settings for the rectangle and oval so that there is no line. You will see that the rectangle or oval is actually somewhat orange-ish and that the background is more pure red.
There is another version of this, which is to replace "red" with " green", "255 0" as the first 2 RGB coordinates with "0 255", and "orange-ish" with "lime-ish".
"This is the only color word which has been traced to an Indo-European root."?
Blue has this: "Through a Proto-Indo-European root, it is also linked with Latin flavus ("yellow"; see flavescent and flavine), with Greek phalos (white), French blanc (white, blank) (borrowed from Old Frankish), and with Russian белый, belyi ("white," see beluga)"...
The ref, in the online etymology dictionary is to "The only color for which a definite common PIE root word has been found."
The same dictionary gives for blue: "PIE *bhle-was 'light-colored, blue, blond, yellow.'"

However, the major exception is the United States. There, red is associated with the right-wing Republican Party. (The reason is that U.S. television networks assigned blue and red to states awarded to the Republicans and the Democrats, respectively, on news maps; the color assignments were alternated every presidential election, but the controversial 2000 presidential election was when commentators happened to pick up on the color choices.)

One of the interesting idiosyncracies of Old English is that the word "red" is frequently used to describe the metal gold. IIRC, the reason for this is that the Anglo-Saxon word for red indicated a slightly different complex of light properties than the modern English word. If this is of interest to anyone working on this article, I can take the time to track down some sources which explain this. -- llywrch ( talk) 15:33, 27 March 2012 (UTC)
Why is red used for the stop signal at traffic lights, etc.? Tabletop ( talk) 15:28, 25 July 2013 (UTC)
Wouldn't it be more appropriate and technically correct to begin this article with "Red is the color of the wavelength of light from approximately 620–740 nm on the electromagnetic spectrum. Next to orange at the end of the visible spectrum, red is the color of blood, rubies, and strawberries, and is commonly associated with danger, sacrifice, passion, fire, beauty, blood, anger, Christmas, socialism, communism, and in China and many other cultures, with happiness." (fns omitted).
Specifically, the edits would be:
Red is the color [begin strike] of blood, rubies and strawberries.[3][4] It is the color [end strike] of the wavelength of light from approximately 620–740 nm on the electromagnetic spectrum.[2] Next to orange at the end of the visible spectrum, red is [insert] the color of blood, rubies, and strawberries, and is [end insert] commonly associated with danger, sacrifice, passion, fire, beauty, blood, anger, Christmas, socialism, communism, and in China and many other cultures, with happiness.[5]
I understand your point of view, but I'm afraid I don't agree. The wavelength of red isn't the main subject of the article; it's mentioned only once in the section on optics. The main subjects of the article are the common uses, appearances in nature, associations and history of the color. The opening citing blood, rubies and strawberries is the description used in the Oxford English Dictionary, and other dictionaries, and I think it's what most people think of when they think of red. Given this, I think that a good lead for this article should reflect the majority of the content of the article and not put so much emphasis on the wavelength. Red is a lot more than just a wavelength of light. SiefkinDR ( talk) 18:53, 27 April 2014 (UTC)
It seems to violate WP:SELFREF. Although it does begin with "Links on Wikipedia and other wikis..." it doesn't provide any sources and if you paste it in a word document, " like this one" doesn't show up as red. Also, it links to WP:REDLINK. Isn't there some sort of consensus against articles in the mainspace linking to project pages, except to disambiguate? If not, there should be.-- 203.100.0.82 ( talk) 23:41, 5 May 2014 (UTC)

Please remove 'fire' from the first sentence of the article, as it is not agreed upon that red is the colour of fire. Flames come in many colours depending on temperature and fuel, and it is certainly debatable that even a common wood fire (which the sentence is likely referring to) is red, as opposed to orange, yellow, or a mixture of colours. 2601:B:AF80:6E9:39D1:B456:381E:12DC ( talk) 08:56, 19 February 2015 (UTC)
I don't think anyone who's read the intro sentence will have failed to scratch their heads at the seeming arbitrariness of the examples used. It seems that the entry on Yellow follows a similar form, but it cites this form as being taken from the Webster's New World Dictionary of 1964. Merriam-Webster Online too has as its primary definition "having the colour of blood," but the justification for this definition seems like it rests on certain etymological associations between the name of the colour and its originally signifying "bloodlikeness" in some languages. Anyhow all I mean to say is that I believe it would make more sense to address what it is in scientific terms before getting on to cultural and etymological significance etc. — Preceding unsigned comment added by Knock-kneed ( talk • contribs) 00:14, 18 February 2015 (UTC)
Acording to the CIE standard observer the human visual system can detect light a wavelengths up to 830 nanometers, which will be perceived as red. The sensetivity is not high, only 1/1000 of the max so it is normally ignored. However it should not, I think, be ignored in the science section. Thorseth ( talk) 20:18, 5 April 2015 (UTC)

Needs a little more. Something like:
Because red is the colour of blood, and Mars is the reddest of the planets, in a number of mythologies Mars is the God of War (because War creates bloodshed). Thus, the symbol for Mars (the same symbol as for "male") is a stylised shield and spear. — Preceding unsigned comment added by 58.164.33.124 ( talk) 02:36, 31 October 2016 (UTC)

According to the Wikipedia Manual of Style, the first paragraph of the lead should explain briefly why the subject is notable. Red is certainly not notable only because of its wavelength, but because it has an important place in nature, history, culture and symbolism. Red as the color of blood, rubies and strawberries are all discussed, explained and illustrated in the article below. SiefkinDR ( talk) 12:34, 10 October 2017 (UTC)
The lead now has twenty-four lines devoted to optics and science and just four lines devoted to the rest of the article. This doesn't work at all. SiefkinDR ( talk) 13:08, 15 October 2017 (UTC)
The lead sentence has to establish the importance of the color in history, culture and nature. Just giving the wavelength doesn't do that. It needs some examples in the first sentence to do that. SiefkinDR ( talk) 09:41, 17 October 2017 (UTC)
There are a surprising number of different variations of wavelength given for red light in Wikipedia, depending upon which article you look at.
There's also a lot of variation in other sources outside Wikipedia.
Do we know that the number in this article is more accurate than other sources? SiefkinDR ( talk) 19:40, 19 October 2017 (UTC)
I propose that we take out the approximate wavelength from the definition in lead paragraph, and simply give the place in the spectrum. As the citation says, it's not an accurate definition; it's just an approximation, it varies because of different conditions, and as the citation itself says, "most colored objects give off a range of wavelengths and the characterization of color is much more than the statement of wavelength." Comments? SiefkinDR ( talk) 07:31, 21 October 2017 (UTC)
Also, this is not the wavelength of scarlet, or the other varieties included in the article, since they're mixtures of different wavelengths of light. Better just to say where it lies on the spectrum, which is correct. Cordially, SiefkinDR ( talk) 09:26, 21 October 2017 (UTC)
Almost all reds are a combination of the wavelength of red with wavelengths of other colors, so I've added "dominant wavelength" to the lead, and a link defining it. I have also added a line to the lead noting the range of reds, including some prominent examples like crimson and scarlet, which are described and illustrated in the article. SiefkinDR ( talk) 07:48, 23 October 2017 (UTC)
Survey here to see who thinks we should have citations in lead. Are any of these points controversial enough to require a citation in the lead. Post below: Cas Liber ( talk · contribs) 07:22, 7 October 2017 (UTC)
A car is a four-wheeled vehiclemight skip having a cite because, in fact, a few cars have 3 or 6 wheels; the statement in the lead is giving a good general impression definition without getting bogged down into technical details that would defeat the purpose of the lede (as long as the details, like the other-wheeled cars, are fully and explicitly noted and cited elsewhere). From what I see on this Talk, the lede has some issues as already noted. Those issues should be sorted out before getting into cites for the parts of the lede under discussion. (On the wavelength, I think it's fine the lede has this, stated as "approximately", without needing a cite, if in the next section or two all the details of wavelength are fully stated and cited. After all, the equivalent info is in the infobox anyway. Just my opinion, of course.)

Hello! There is a mistake in the introduction: "It is a primary color in the RGB color model and the CMYK color model, and is the complementary color of cyan."

Currently I am checking all of the citations in this article. I am remaking all simple <ref> citations into their scripted counterparts. At the same time I try to add more relevant info if it is not already there. If needed, I also add archived versions. All of the information that is correct will stay as it was, including the date that the citation was added.
The biggest change I am going to do within citations is grouping all of the citations corresponding to Bibliography into single citation entries. That way it is possible to significantly reduce the number of citations. The page number that the citation is referring to in that sentence / paragraph is going to be displayed using the rp template. I would suggest other contributors to try using this template instead of creating multiple citations regarding the same work.
As for the Bibliography itself, even though it is going to be a duplicate of the citation entries, I think it should stay as it is. It is a shorter list of the most important works that this article was based on.

In section 6 "In Religion" or section 14 "Superstition" there should be a section about Paganism and/or Wicca. A bulletin could be placed stating "In modern Pagan and Wiccan religions, red is representative of the Root Chakra, the Chakra that grounds us to the world. It also is representative of energy, passion and courage. It is believed that when we don't have enough red in our lives we become fearful and lazy, and when we have too much we become angry, agitated and demanding" [1] Gagehannan ( talk) 00:42, 16 December 2019 (UTC) Gagehannan ( talk) 00:42, 16 December 2019 (UTC)
First, colors don't have history, so that article really should be History of red in human culture or such. The topic is interesting, but I am unsure it warrants a stand-alone article, and I think readers will be best served if this is integrated here. Also, this article talks about this topic in many sections, to WP:POVFORK is also an issue. Really, the difference is that the new article presents a chronological overview, while the old one here provides an overview by topic.

Red is one of the most favorite colors in the world. Judging that it has a bright opacity which attracts people
The explanation of the effects of Dichromacy is incorrect.
Red objects won't appear grey to a dichromat but rather a dark yellow depending on the distance to the absorption maximum of the yellow cones. Light with wavelengths greater than the absorption maximum of the yellow cones (i.e. light that appears orange or red to humans) will still appear yellow to a dichromat but darker because of the reduced absorption in this region. Sufficiently long wavelengths will have no absorption and thus look black. The human analoge is red objects that emit wavelengths greater than the absorption maximum of the red cones of humans. These wavelengths appear dark red or black to humans but not grey.
It is however true that green objects will appear grey to a dichromat because the green wavelengths fall in the area between the absorption maxima of the yellow and blue cones which are the complementary colors of a dichromat (with blue-yellow vision). Since a dichromat can distinguish only two colors, a mixture of light of these colors will appear white, grey or even black depending depending on the overlap of the absorption spectra of the blue and yellow cones respectively.
