Biological neural architecture for chromatic adaptation resulting in constant color sensations

A multistage color model (De Valois, 1993) was modified and extended to a color appearance model of parvocellular foveal color vision realizing a chromatic adaptation inside a physiologically motivated fundamental color space. This results in prediction of color appearance of object colors under various states of adaptation. During the observation of several scenes there is an endeavour to move toward a steady state color-context independent model. By this way an average level of color sensation synonymous with constant color sensations is achieved
