展示了暴露在强绿光下的恒河猴的色调辨别、光谱灵敏度以及两者的数学模型。在之前的实验过程中，猴子的一只眼睛出现蓝盲，另一只眼睛颜色正常。绿光暴露的结果显示，这两种测量的敏感性都有所下降，其中蓝盲眼的敏感性损失更大。尽管蓝绿色光谱区域的色调辨别力有相当大的损失，但最佳辨别点 590 nm 处的色调辨别力仍然不受影响。这种结果模式给色调辨别模型带来了困难，并导致所提出的模型采用三个相反的颜色通道。通过从光谱灵敏度导出用于对色调辨别进行建模的参数，可以最大程度地减少自由参数的数量，并增强光谱灵敏度和色调辨别之间的集成，反之亦然。
Hue discrimination, spectral sensitivity, and mathematical models of both are presented for a rhesus monkey which was exposed to intense green light. One of the monkey's eyes was blue-blinded in a previous experimental procedure and the other was color normal. The results of green light exposure showed a loss of sensitivity on both measures, with greater loss in the blue-blinded eye. Although there was considerable loss of hue-discrimination in the blue-green spectral regions, hue-discrimination at the point of best discrimination, 590 nm, remained unaffected. This pattern of results poses difficulties for models of hue discrimination, and has resulted in the proposed model employing three opponent color channels. The number of free-parameters are minimized and the integration between spectral sensitivity and hue discrimination enhanced by deriving parameters used in modeling hue discrimination from spectral sensitivity or vice versa.
