The color of human skin of 241 whites, blacks, and orientals was measured by reflection spectrophotometry. Among these groups, major differences in luminous reflectance and excitation purity, but not in dominant wavelength, were observed. The twin absorption bands of oxyhemoglobin at 540 and 580 nm were more prominent in whites (particularly females) than in orientals or blacks. Parameters determined for Source A were higher than those for Source C.
通过反射分光光度法测量了241名白人、黑人和东方人的皮肤颜色。在这些群体中，观察到在发光反射率和激发纯度方面存在主要差异，但在主波长方面没有差异。氧合血红蛋白在540和580纳米处的双吸收带在白人（尤其是女性）中比在东方人或黑人中更明显。为源A确定的参数高于为源C确定的参数。
