@Sjoerd I look forward to your answer. I don't imagine that the computation itself is that involved but the derivation is. Individuals see color differently, and perceived color depends greatly on contrast, illumination (both spectrum and intensity, e.g. Kruithof curve), field of view, adaptation, etc. I suppose though these effects are to be ignored and a "standard observer" used however. Since commenting I learned that version 10 now includes LABColor and XYZColor which if correctly implemented should simplify conversion to monitor RGB.

Mathematica already has some color transformation functions available, so I thought there might be some easy way to relate the matrix transformations to built-in Mathematica functions. | |

| Aug 15, 2014 at 0:48 | comment | added | Mr.Wizard | @halirutan Within the gamut limitation of the display that is a standard assumption. It is far from simple however. Guillochon, even a basic introduction to color theory shows that this is not a simple subject. I am inclined to close this as "requires the services of a professional consultant." Without an algorithm to implement the vast majority of work on this doesn't specifically relate to Mathematica. I dabbled in this stuff in the past but I never knew enough to derive an algorithm and I've forgotten much. | |
