Case of Congenital Tritanopia with Implications for a Trichromatic Model of Color Reception*

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