Racial differences in color vision: do they exist?
The present experiment investigated the possibility that variation in fundus pigmentation among individuals may be related to differential color sensitivity. Fifty black and white observers representing a wide range of skin (and fundus) pigmentation made direct heterochromatic brightness matches for a white standard field against each of five chromatic comparison fields. Results indicated that pigment (i.e., racial) differences in color vision do not exist, as measured by the two psychophysical methods used. The data showed that the heterochromatic matches were less reliable for the more saturated colors, violet and red, and also that the psychophysical methods used to obtain the matching data differentially influenced the results for the more saturated colors.
