Abstract

In previous papers the writer has formulated a theory of color vision in which chromaticness is subserved by independent red-green and blue-yellow mechanisms. Each mechanism involves two photosensitive substances. The relative rates of response of these substances for the various wavelengths can be determined from color mixture and adaptation data for normal observers, and this has been done. The present paper makes use of certain assumptions about the color mixture data of the tritanope and the luminosity curve of the normal observer to derive the response curves for the four photosensitive substances subserving color vision.
