A woman's complexion color is an important and familiar factor in the evaluation of preferred color appearances under illumination. For this reason, a new method of estimating preference for Japanese complexion color under illumination is proposed is the present study. T clarify the relationship between preference for Japanese woman complexion under illumination and the chromaticity coordinates of the complexion on the CIE 1976 u' v' chromaticity diagram, we analyzed subjective evaluation data obtained by evaluating the color appearance of 40 complexions by using seven evaluation categories in detail. A new preference index PS for Japanese complexion color under illumination was derived from the experimental results. It was clarified that the new index PS correlated well with not only the experimental data but also with preference for Japanese woman complexion color under illumination produced by various kinds of light sources adopted. The new index PS can evaluate the preferences concerning Japanese woman complexion color related to light sources better than the standard illuminant D_<65>, which can not be evaluated by the present index R_a proposed by CIE and JIS. The preference index for the complexion color PS proposed in the present study will be useful related to a practical estimation index of the color rendering properties of light sources from the viewpoint of preference of complexion color.
