An opponent-process theory of color vision.

Abstract

The two major theoretical accounts of color vision are those classified as the Young-Helmholtz and the Hering types of theories. For many years the former has been judged by most work-ers in the field to provide the simplest explanation of the way in which light stimuli give rise to color sensations. The advantages that appear to favor the Young-Helmholtz three-component hypothesis are two: it is parsimonious, and its postulates are easily quantifiable and hence subject to precise experimen-tal test. In its parsimonious and easily quantifiable form, the theory is simple:
