Fundamental Response Functions and Binocular Color Matching

A method is described for determining the fundamental response functions of the Young-Helmholtz three-receptor hypothesis by means of binocular color matching data. The method is an extension of the methods described previously by Wright and by Walters. Data supplied by Burnham, Evans, and Newhall are used to determine a set of the functions. These results are compared with those obtained previously in adaptation experiments and with those implied by results of color blindness investigations.
