In this research, color appearance of light-source and surface color stimuli in a wide range of color space were measured by the psychophysical experiments. 1. For surface color stimuli, 424 OSA color charts were presented and the observers described the color appearance of each stimulus by monolexemic color name (categorical color naming). The results showed that there exist eleven color names in all well-developed languages, and that a color space can be divided into eleven basic categories by these color names. 2. For light-source color stimuli, 195 different color lights almost equally placed in the CIE1976u'v'chromaticity diagram were presented and the observers described the color appearance of each stimulus by 1)the ratio of chromatic and achromatic component (saturation), 2)the ratio of red, yellow, green, and blue component (hue). The results showed that the coincidence of each unique hue area among observers is good in high purity region while individual differences increase in low purity region. The result of the direct comparison between light-source and surface color stimuli showed that light-source stimuli appear less saturated and more yellowish that the surface color stimuli of the same chromaticities.

本研究通过心理物理学实验测量了光源和表面颜色刺激在宽范围颜色空间中的色貌。1.对于表面颜色刺激，424 OSA颜色图表，并观察员描述的颜色外观的每个刺激的monolithic颜色名称（分类颜色命名）。结果表明，在所有发达的语言中都存在着11个颜色名称，颜色空间可以根据这些颜色名称划分为11个基本类别。2.对于光源颜色刺激，呈现了几乎相等地放置在CIE 1976 u 'v'色度图中的195种不同颜色的光，并且观察者通过1）彩色和非彩色分量的比率（饱和度），2）红色、黄色、绿色和蓝色分量的比率（色调）来描述每种刺激的颜色外观。结果表明，在高纯度区域，观察者之间的每个独特色调区域的一致性较好，而在低纯度区域，个体差异增大。光源与表面色刺激的直接比较结果表明，光源刺激比相同色度的表面色刺激显得更不饱和，更偏黄。
