Racial Differences in Color Vision; Do They Exist?

Key Points

The aim was to explore if variations in fundus pigmentation affect color sensitivity among races.
Conducted brightness matches for a white standard field across five chromatic comparison fields.
Included fifty black and white observers with diverse skin and fundus pigmentation.
Employed two psychophysical methods to measure color vision sensitivity.
No significant differences in color vision related to pigment variations were found.
Unreliable data noted for saturated colors like violet and red.
Results indicated that the methods used influenced outcomes for more saturated colors.

Abstract

ABSTRACT 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 representinga wide range of skin (and fundus) pigmentation made direct beterochromatic brightness matches for a white standard field against each of five chromathic 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.
