PHYSICS OF COLOR FORMATION

In this article issues related to the introduction of the concept of color temperature used in the colorimetric measurements are briefly discussed. An ambiguity of existing definition of color temperature is stressed. An unambiguous definition of color temperature and the technique of its implementation are suggested. Also a physical interpretation of the RGB color model is suggested which introduces the carriers of colors-complexes of photons. The thermodynamics of these complexes is studied. This will help to find new description of color formation which is oriented on human perception but is not connected with any observer.
