Abstract: The skin colors of 548 Chinese children and youths aged from 3 to 17were measured by a colorimeter, tristimulus values (X. Y. Z) and chromaticitycoordinates (x.y) were obtained. The results show that the chromaticitycoordinates of average skin colors of Chinese children and youths arex=0.3828, y=0.3454; reflectance=26.0％; dominant wave length λd=590.2nmand excitation purity Pe=27.4％. The reflectance of skin of females ishigher than that of males in every age group and it decreases with age.The excitation purity of skin colors of females is somewhat lower than thatof males, and saturation of skin colors increases with age. Comparing thoseresults with that obtained for Chinese adults, this refectance is higher byabout 3％, saturation is lower by about 4％ and the dominant wavelength is longer by about 0.9nm.
