Diagram

Any comments on this diagram? Does it illustrate the effect? Are there any good references/sources for illustrating this effect that anyone can recommend? thanks, pfctdayelise (talk) 12:43, 21 August 2008 (UTC)[reply]

Looks like more of a demonstration of blown out highlights to me. ie. these colours ACTUALLY DO have different hues. --GregE (talk) 14:29, 21 April 2011 (UTC)[reply]

I'm not sure whether it illustrates the effect or not -- the questions are whether the pairs on the left side both have the same hue, and whether the color being added at each step is white (or rather gray). The latter point is particularly of concern, since "white" is a somewhat arbitrary concept and may differ across monitors. One way or another, I think the final version would illustrate the effect as well as the animation, and would be preferable. (Personal opinion: I HATE animations that I can't turn off, as they are a constant drain on my attention.) Regards, Looie496 (talk) 19:36, 21 April 2011 (UTC)[reply]

I think I solved the mystery of the diagram. One starts with the leftmost color, and each progression to the right averages each of the three RGB values with 255 (of white). This is unfortunately wrong: sRGB is gamma-corrected so direct averaging would not reflect a physical blending of light. --Artoria2e5 🌉 06:21, 19 February 2021 (UTC)[reply]
- I have no idea how to fix it yet. The best way should be regenerating the entire image, maybe making it not an animation this time. But writing code for image generation? Oh no. --Artoria 2e5 🌉 06:37, 19 February 2021 (UTC)[reply]
