Abstract

The luminous efficiency of the spectrum, dichromatic coefficients, spectral color confusions, and matches of spectral to pigment colors were obtained on a congenital tritanope. The results are compared with those obtained by Wright and by Thomson and Wright. The conclusion is drawn that a point close to the spectrum locus in the violet region of the normal chromaticity plane has been reliably located as representing a “missing” receptor process, according to the Helmholtz theoretical development. The possible implications of this finding are pursued with reference to the theoretical primary receptor functions of normals and the question of a theoretically derived equal chromaticity space.
