The Possibility of the Color Aptitude Test as a Color Deficiency Test

Alfred S Casola, Fordham University

Abstract

It is an accepted fact that the color vision of some persons differs from that of the normal. If the deficiency is mild the person possessing it is said to be color anomalous, if the deficiency is severe he is said to be color-blind. This term is incorrect and unfortunately suggests that such persons all have the same color vision, and all are blind to color, which, however, is not the case. The outstanding characteristic of these persons is their confusion in recognising and naming colors. This is indicative of a reduced power to discriminate colors, and implies that the total number of discriminable colors which such a person can see is significantly smaller than that recognized by a person with normal vision (21). As a result of this reduction, color-blindness is a deficiency, and not a difference, in visual capacity. Despite many attempts to eliminate this erroneous and misleading term, "color-blindness" has persisted to the present day to describe these deficiencies.
