Color-subspace-based color-coordinate system

Color is a sensation normally produced by light. For reasonable handling of the spectrum reflected from the surface of a sample one needs a finite dimensional coordinate system. There are several different bases and frameworks to define color coordinate systems. One goal is to find an uniform coordinate system which also could emulate human color vision mechanisms. In this report we describe the color subspace color coordinate system, which is shown to be adaptive and accurate coordinate system for different uses. Also, the subspace approach for human color vision system is represented. This model is based on the Young-Helmholz theory with opponent colors modelling color preprocessing in the LGN-level. It is shown that this approach allows an adaptive way to define color coordinate system for many different purposes. The proposed coordinate system gives an unified view into the color definition and color representation problem.
