The differential chromaticity thresholds obtained by varying degrees of metamerism have been evaluated for five target chromaticities. Differences have been found between the chromaticities predicted by the CIE-1931 standard observer and those actually observed under our experimental conditions, with foveal fields of 3 degrees, luminance within the low photopic level, and sets of primary colors produced by filters of differing spectral bandwidths. Failures of colorimetric additivity under these experimental conditions are discussed. The results have also been analyzed by using other sets of color-matching functions, i.e., Judd's proposed modification at short wavelengths and also the supplementary standard observer, CIE-1964.
针对五种目标色度，评估了通过不同程度的同色异谱获得的色差阈值。在3度中央凹视野、低明视觉水平亮度以及由不同光谱带宽滤光片产生的原色集的实验条件下，发现CIE - 1931标准观察者预测的色度与实际观察到的色度之间存在差异。讨论了在这些实验条件下比色相加性的失效情况。还使用其他颜色匹配函数集对结果进行了分析，即贾德提出的短波长处的修正以及补充标准观察者CIE - 1964。
