我们报告了匹配实验的结果，该实验旨在研究在不同模拟光源下在CRT显示器上呈现的物体的颜色外观。受试者在具有不同光谱功率分布的光源下渲染的标准对象和测试对象之间设置不对称的颜色匹配。对于任何光源变化，我们发现匹配标准和测试对象的锥坐标之间的映射可以用对角线线性变换来很好地逼近。从这个意义上说，我们的结果与von Kries的假设是一致的。物理。Menschen 3,109(1905)[摘自《色觉来源》，D.L.麦克亚当主编。(麻省理工学院出版社，马萨诸塞州剑桥市，1970)]}这种适应只是改变了不同锥体类别的相对敏感度。此外，我们还考察了对角线变换对光源变化的依赖关系。对于所测试的光源范围，我们发现线性变换的对角线元素的变化是光源变化的线性函数。
We report the results of matching experiments designed to study the color appearance of objects rendered under different simulated illuminants on a CRT monitor. Subjects set asymmetric color matches between a standard object and a test object that were rendered under illuminants with different spectral power distributions. For any illuminant change, we found that the mapping between the cone coordinates of matching standard and test objects was well approximated by a diagonal linear transformation. In this sense, our results are consistent with von Kries's hypothesis {Handb. Physiol. Menschen 3, 109 (1905) [in Sources of Color Vision, D. L. MacAdam, ed. (MIT Press, Cambridge, Mass., 1970)]} that adaptation simply changes the relative sensitivity of the different cone classes. In addition, we examined the dependence of the diagonal transformation on the illuminant change. For the range of illuminants tested, we found that the change in the diagonal elements of the linear transformation was a linear function of the illuminant change.
