PURPOSE:To indicate color of a made-up skin by estimating it from reflectivity of a surface made up by applying a coat of a cosmetic onto 2 pieces of smoothness measuring plates which do not absorb oil and moisture contents of the cosmetic. CONSTITUTION:Onto 2 pieces of smoothness measuring plates which are provided with surface coating so as not to absorb oil and moisture contents of a cosmetic and have reflectivities of R'g1(lambda) and R'g2(lambda), the costmetic is applied to a film thickness of X which is permeable at 400-700nm. And, after reflectivities R'1(lambda) and R'2(lambda) of the coated surfaces are sought by aspectophotometer, compensation of mirror surface of a reflectivity measuring device is made with respect to these reflectivities. An inherent reflectivity R infinity (lambda) is sought from reflectivities R1(lambda), R2(lambda), Rg1(lambda) and Rg2(lambda) which are sought after the compensation, and S is sought from Equation (I) or Equation (II). Further, by calculating a reflectivity R of a cosmetic-applied skin from Equation (III), applying a compensation of mirror surface reflection of the reflectivity measuring device to R, using a stimulation value given from the reflectivity R after the compensation, and calculating a point on coodinates in the Munsell color system or in equilibrated sensible color space, a skin color position is indicated. |
