虽然面部皮肤的颜色测量在皮肤病学和化妆品中变得越来越普遍，但对面部皮肤中主观颜色感知和色度值之间的关系知之甚少。本研究探讨了日本女性面部皮肤颜色的明度、色度和色调角与白度感知之间的可能关系。首先，对日本女性面部皮肤的感知亮度进行了视觉评价，并与度量亮度、色度和色调角进行了比较，讨论了色调和色度对感知亮度的影响。其次，心理物理实验的面部图像和合成的肤色板图像的白度进行了检查的影响，色调和色度的感知白度更精确和独立。两个实验的结果表明，在日本女性的面部皮肤颜色，度量亮度不同意感知的白度或亮度在一个狭窄的亮度范围。在高亮度区域，红色的面部皮肤颜色比黄色的面部皮肤颜色更亮或更白，并且低色度的面部皮肤颜色比高色度的面部皮肤颜色更亮或更白。然而，在彩色板图像中，不能确认由色调引起的感知白度的变化，并且由色度引起的感知白度的变化比来自面部图像的变化弱。这些结果表明，一个更高层次的人脸识别过程影响的白色知觉，面部皮肤白度的标准是由面部肤色分布。(c)2011 Wiley Periodicals，Inc.

Although the color measurement of facial skin becomes more common in dermatology and cosmetics, little is known about the relationship between subjective color perception and colorimetric values in facial skin. In this study, the possible relationships among perceived whiteness and the metric lightness, chroma and hue angle of Japanese females' facial skin color were investigated. First, the perceived brightness of the facial skin of Japanese females was evaluated visually and compared with metric lightness, chroma and hue angle, and the effect of hue and chroma on the perceived brightness was discussed. Second, a psychophysical experiment on the whiteness of the facial images and synthesized skin color plate images was conducted for examining the effect of hue and chroma on the perceived whiteness more precisely and independently. The results of two experiments showed that in regard to the facial skin color of the Japanese female, metric lightness disagrees with perceived whiteness or brightness in a narrow lightness range. The reddish facial skin color appeared brighter or whiter than that of a yellowish one in high lightness regions, and the low-chroma facial skin color appeared brighter or whiter than a high-chroma one. However, in the color plate images, a change in perceived whiteness by hue could not be confirmed, and the change in perceived whiteness by chroma was weaker than that from facial images. These results indicated that a higher-level process of face recognition affected whiteness perception, and the criterion of facial skin whiteness was determined by facial skin color distribution.
