On the merits of model making in understanding color‐vision phenomena

摘要

AbstractSince 1962, I have intermittently been engaged in problems of color‐vision modeling, intrigued by some apparent inconsistencies in the original Walraven color‐vision model. This has carried me into problems of receptor action spectra and densities, of gain control and chromatic adaptation, and of the concept of luminance as a linear or nonlinear combination of receptor inputs. By taking a simple physical model as a start and adding physiological elements whenever the quantitative predictions failed, we hope to have gained some insight into the color‐vision mechanisms. This review is intended to enable a discussion of the limitations and merits of this rather theoretical app
