While significant progress has been made toward achieving chromaticity constancy, recent work has shown that the most advanced algorithms are unable to render chromaticity stable enough so that it can be used as a cue for object recognition [B.

Mechanisms of color constancy M. International Journal of Computer Vision 42 3, First, given an RGB image of a scene viewed under any illuminant, we can trivially synthesize the same gray-scale image we simply code the invariant coordinate as a gray scale.
In computational terms we can solve the color constancy problem if device red, green, and blue sensor responses, or RGB’s, for surfaces seen under an unknown illuminant can be mapped to s RGB’s under ay known reference light. We show that there exists a single invariant color coordinate, a function of R, G, and B, that depends only on surface reflectance. We present experiments that show that invariant gray-scale histograms are a stable feature for object recognition.
