Abstract:

This paper discusses the possibility of constructing an equal-contrast color space based on the mathematical apparatus used in Einstein’s general theory of relativity. Such a construction makes it possible to avoid the drawbacks inherent to the color spaces that are currently known and used—namely, the difference of the sizes of the MacAdam ellipses, depending on the chromaticity of the stimulus.

Keywords:

color locus, color separation thresholds, color horizon, Mac Adam ellipses, Einstein equation, color tone, color saturation, color tensor
