The color-matching functions of individual tritanopes differ significantly from those predicted with the assumption that the two cone pigments of the tritanope are those which underlie the matches of the standard observer. The differences cannot be explained completely by the abnormal luminosity curve of the standard observer nor by abnormalities in transmissivity of the eye media. Individual tritanopes differ significantly in their color matches in ways not entirely accounted for by eye media differences. The results are consistent with the view that there are a variety of different long- and medium-wave-sensitive cone visual pigments among different tritanopes.
