Abstract

The “Color Aptitude Test” sponsored by the Inter-Society Color Council is now a well-developed, color-matching test consisting of saturation series of carefully prepared chips in four colors. Colorimetric and spectrophotometric specifications have been presented. Analysis of some 1000 testings indicates (1) a satisfactory regularity of spacing of the chips, (2) a near normal distribution of total scores derived from weighted scores per “match,” (3) good test-retest reliability consistent with high sensitivity of discrimination, and (4) a measure of reliability of individual performances in terms of test to retest change in score.
