To find the chromaticity coordinates of the ＇＇Preferred Complexion of Japanese Woman＇＇ under illumination, subjective estimation experiments were conducted on the complexions of 3 female models under each of 40 colors of illumination. The chromaticity coordinates of ＇＇Preferred Complexion＇＇ for ach model were about the same together. The average chromaticity coordinates of 3 female models were (u＇, v＇) = (0.2425, 0.4895) under the standard illuminant D65. The ＇＇Preferred Complexion of Japanese Woman＇＇ in this experiment was compared with the ＇＇Preferred Complexion of Caucasian Woman＇＇ studied by Sanders. The ＇＇Preferred Complexion of Japanese Woman＇＇ was shifted to a slightly higher saturation and reddish in hue, compared with the actual complexion of ＇＇Japanese Woman.＇＇ On the other hand, the ＇＇Preferred Complexion of Caucasian Woman＇＇ was orange in hue, the same as the actual complexion of ＇＇Caucasian Woman.＇＇ The color shift of saturation of the ＇＇Caucasian Woman＇＇ was 3.5 times as large as that of the ＇＇Japanese Woman.＇＇
