"Colour banding is more present with relatively low bits per pixel (BPP) at 16–256 colours (4–8 BPP), where not every shade can be shown because there aren't enough bits to represent them." This sounds more like posterisation since it is not necessarily a function of colour saturation. Banding occurs when multiple colours in a wide gamut are clipped to the boundary of a limited gamut. This means that several tones of a hue are mapped to the same colour, flattening out any modelling or rounding that these tone gradients might have been representing, e.g. the curved cylinder of a Royal Mail post pillar. —Preceding unsigned comment added by Hfinger ( talk • contribs) 04:54, 13 June 2008 (UTC)
The image to the Article is not right, its shows the problem of banding, but it labes an 8 color(3bit) gradient as 8 bit gradient(but the right image repesents an 8 bit gradient, since its only one color channel which is usually 8 bit)
The 24bpp spectrum looks convincing... but if you blow it up banding will become very apparent. Don't ask me how many bpp would be necessary to satisfy the human eye, but its much better than 8bits per colour channel. This is a problem for video games for example. A large swath of sky can be very banded if it doesn't transition through very many shades very quickly throughout. -- Truth Glass ( talk) 01:29, 13 January 2012 (UTC)
I fixed everything that I could to fix the misspelling of the word "color", but I couldn't change title.
"Because the banding comes from limitations in the storage of the image, blurring the image does not fix this." 1) it's not about storage, as it's properly explained in the first paragraph. 2) blurring obviously could fix it, because blurring is effectively dithering image. And indeed blur is one of the simplest ways to deal with it. It's a Gimp's built-in lens blur I used on it - https://imgur.com/FFaomuO - it has some darker strips all over, but that's because original image doesn't show bands, but a few banded gradients, which would be a third issue. 89.69.127.250 ( talk) 14:37, 15 August 2021 (UTC)
I think this article can be made more coherent with posterization, i.e. make them both complement and cooperate with each other, since both of these articles are looking at the same effect by different perspectives (art versus computer graphics). 172.218.5.205 ( talk) 05:50, 3 April 2022 (UTC)
