通过一系列的行为辨别实验，研究了三只家养狗的色觉。增量阈值光谱灵敏度函数的测量和颜色匹配的直接测试表明，狗的视网膜包含两类视锥光色素。计算出这两种颜料的光谱峰分别为429 nm和555nm。色觉测试结果均与狗具有二色性色觉的结论一致。
The color vision of three domestic dogs was examined in a series of behavioral discrimination experiments. Measurements of increment-threshold spectral sensitivity functions and direct tests of color matching indicate that the dog retina contains two classes of cone photopigment. These two pigments are computed to have spectral peaks of about 429 nm and 555 nm. The results of the color vision tests are all consistent with the conclusion that dogs have dichromatic color vision.
