Hmmm... this is definitely only a poor stub. And a spectrophotometer does not have to have 31 channels, although merely a "better" colour-gauging device may. A spectrophotometer should have as many channels (or resolution) as is needed to accurately characterise whatever it is you're trying to measure. 2nm bin-size and a few nm FWHM is not hard to get for some $1000's.
I agree with the others that the page needs to start by "setting the scene" of what colourimetry is (and what it isn't), then the basic premises of the numerical approaches (or links to relevant articles), before going on to applications and instrumentation (or, again, linking).

We gotta make this page mor related to what a person in the field of Colorimetry does. Yes, they use all the devices, but for whom and why and what are challenges, and move allthe device pages over to this page: Spectrophtometer (visual) spectroradimeter colorimeter, etc.

There isn't enough emphasis on the subjective nature of color - the fact that the calculations all rest on psycho-physiological experiments, and that various color models exist to bring out and quantify thigs that are in the end perceptive phenomena.
i need to now how colirmetry is used in industry and its back ground information if sum one knows then can u plz tell me thnk u

The word colorimetry is used by scientists working in different areas. On the one hand, it's used in color science, photography, printing and graphic communication industry. On the other hand, it's used in chemistry. On the one hand, colorimetry is the science and technology used to quantify and describe physically the human color perception. On the other hand, colorimetry is a method of analytical chemistry which is used for identification and determination of concentrations of substances that absorb light. Obviously chemists don't care about how colors are perceived by humans, the goal is to measure concentration of a substance. Similarly photographers don't care about how to measure concentration of a substance, the goal may be to get adequate color reproduction. Although the same instruments are used in both areas, it doesn't seem to be a good reason to merge these two topics into the same article. Actually I was going to add some new content to this arcticle, in particular, information on color matching experiments and I believe it will be confusing to people looking for information on chemical methods. So I think that it would be good to separate these topics into different articles.
Is there a primary topic? Well, I would say that the primary topic is color perception. But I'm afraid chemists will tend to disagree with me. Let's try to search Google and look at the first page: http://www.google.com/search?q=colorimetry. We find both meanings there. By the way, encyclopedia Britannica says that colorimetry is a chemical method (the link is on the first page). How this word is used in Wikipedia? Let's take a look at http://en.wikipedia.org/?title=Special:WhatLinksHere/Colorimetry&limit=500. It looks like there's no primary topic.
So my proposal is to make this page the disambiguation page.
Dear Wikipedians, what are your opinions?

split the page already. these are two completely separate technologies; if i understand, the chemical application seems directed to measuring solute concentrations and has nothing to do with color per se, merely specific wavelengths where transmission is measured.

Alexander has now added a split proposal template, as I suggested he should have done in the first place. But I think the split has already been done, so it's not clear what else we need to say. Comments? Dicklyon ( talk) 14:51, 16 June 2009 (UTC)
I cannot find any credible reference to this being the correct spelling in British English. As far as I am aware it is colorimerty in ALL variations of English. —Preceding unsigned comment added by 80.238.1.135 ( talk) 21:15, 22 January 2011 (UTC)

I bet it'd be hard to distinguish, for example, the eye-sight perception of shrimp at this stage in science: but seeing as there is (putatively?) human tetrachromats, has there been any attempts at classifying by means of colorimetry the varying degrees of tetrachromacy? 66.96.79.217 ( talk) 21:26, 16 May 2016 (UTC)

The color "white" is fundamental to colorimetry and color science, but most of that article's editors see the article as being primarily about the cultural usage, figurative associations, and history of "white" (and no more fundamental than any other color like orange), rather than stating or explaining what white literally is as a color, which is well-understood in color science. Could any of you weigh in on the current dispute on the talk page talk:White there, which mainly is between just two editors about the lead and its first sentence? One of them wants the first paragraph to rely first on citing illustrative examples of white like snow, chalk, and milk, before even defining white in any objective sense, and based largely on one colloquial dictionary definition of the word "white".

if we could actually meausre colour in any objective way, then we would actually know what colour that picture or the dress is, but as the wiki page for "the dress" clearly states, that is not the case. 2001:56A:7D81:BF00:DCB8:E504:3EF3:EFC2 ( talk) 02:13, 30 May 2023 (UTC)
