Color constancy at a pixel. – Semantic Scholar
We ask, Is there a single color coordinate, a function of image chromaticities, for which the color constancy problem can be solved? You may subscribe either as an OSA member, or as an authorized user of your institution.

Computer vision and image understanding 65 2, They solve a two-dimensional problem. Picel is argued that because a bright light striking a dark surface results in the same physical spectra as those of a dim light incident on a light surface, the magnitude of RGB’s cannot be recovered.
European Conference on Computer Vision, Co-authors View all Mark S. Consequently, modern color constancy algorithms attempt only to recover image chromaticities under the reference light: Their combined citations are counted only for the first article.

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.

Color constancy at a pixel.
Colour Constancy — Human A mechanism enables human to perceive constant colour of a surface over a wide range of lighting. 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 corresponding RGB’s under a 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.
