I studied the subject because I was interested in making red-cyan anaglyph stereograms https://en.wikipedia.org/wiki/Anaglyph_3D and found out that if you have a high color gamut monitor and ask for (r,g,b)=(0,255,0) in sRGB you really get something like (15,238,15) and that little bit of red goes through the lens on the wrong eye and causes crosstalk. This can be solved by outputting (0,255,0) in the color space of the monitor or barring that (say you are displaying on the web) in some color space like Adobe RGB, Display P3 or Rec 2020 which has primaries closer to what your monitor has. I found thoroughly understanding this spec was helpful https://www.color.org/specification/ICC.1-2022-05.pdf and helped me get in control of colors. Of course there is a lot more to it in terms of understanding perceptual aspects of color spaces, how to systematically pick colors that work well together, etc. |
