Grassmann’s Law gives a clue how to create a color sensation in the brain by mixing up some wavelengths out of the spectrum. The CIE finally defines what is visible for a “Standard Observer” and Microsoft & HP (sRGB) and Adobe (Adobe RGB) build their color spaces on that foundation.
Then I organize a shootout between sRGB and Adobe RGB – and I’ll stick to sRGB for the forseeable future.
Finally I cover the question of Intent while converting between different color spaces – Perceptual or Relative Colorimetric?
