Abstract

In order to clarify the relationship between the evaluation of the complexions of Japanese women and their chromaticity coordinates for various chromatic adaptations, a series of experiments were conducted. The complexions of three female models were estimated under 40 kinds of illumination by the semantic-differential method using 31 adjective pairs rated by 20 observers on the chromatic adaptations of 3000K and 4200K, to compare them with previous results on the chromatic adaptation of 6100K.
Evaluations of human complexions under the illuminations were determined by two main factors, “activeness” and “refinement” on various chromatic adaptations. The factor score for “activeness” correlated well with the u' value of the corresponding color to D65 adaptation using the CIE chromatic adaptation formula, when it was less than 0.25. The u' value of about 0.25 was the maximum value for the evaluation of“activeness”. The highest factor score for“refinement” had almost all the same chromaticity coordinates for the various chromatic adaptations. The factor score became lower as the chromaticity coordinates of the human complexion under the illumination became further from that having the highest factor score.
