The purpose of our research was to investigate color discrimination under conditions of ambient illumination that may reduce CRT display saturation and contrast. Our research measured both the variability of color matching and the offsets from a match necessary for a 100% discrimination difference. We did this for four dominant wavelengths each at five saturation levels. Our subjects were tested at low, medium, and high adaptation levels for both large and small test stimulus sizes. In general, our results for the low luminance color matching conditions are in agreement with the published literature. For the high luminance and small field conditions, our data suggest that color discrimination should not be predicted from the 1960 CIE Uniform Chromaticity Space data. Color discrimination varies dramatically with dominant wavelength; reds and greens are more difficult to discriminate than yellows and yellow-greens.
我们研究的目的是调查在可能降低阴极射线管（CRT）显示器饱和度和对比度的环境光照条件下的颜色辨别能力。我们的研究测量了颜色匹配的变异性以及实现100%辨别差异所需的匹配偏移量。我们针对五个饱和度水平下的四个主波长进行了此项操作。我们的受试者在低、中、高适应水平下接受了大小不同的测试刺激的测试。总体而言，我们在低亮度颜色匹配条件下的结果与已发表的文献一致。对于高亮度和小视场条件，我们的数据表明，不能根据1960年国际照明委员会（CIE）均匀色度空间数据来预测颜色辨别能力。颜色辨别能力随主波长的变化极大；红色和绿色比黄色和黄绿色更难辨别。
