A multicolored display was illuminated by 3 bands of wavelengths corresponding to the maxima of the spectral sensitivities of the 3 types of photoreceptors found in the bee retina. The intensity of each band could be varied individually. The light fluxes emitted by the colored areas of the multicolored display were determined quantitatively. Free-flying honeybees were trained with sugar solution to choose one of the colored areas. The illumination was then changed in such a way that the light fluxes formerly emitted by the training area were now measured on another area. When the trained bees were tested under those conditions, they still chose the training area. The relative positions of the colored areas were changed in order to exclude learning of position. It is concluded that color vision in bees is, in a certain range, independent of the spectral content of the illumination. Model calculations show that the behavior observed in bees is consistent with the retinex theory (Land, 1977), i.e., an algorithm using long-range interactions is required to explain color constancy.
一个彩色显示屏由3个波长带照亮，这3个波长带分别对应于蜜蜂视网膜中发现的3种光感受器的光谱敏感度最大值。每个波段的强度可以单独变化。对彩色显示屏彩色区域发出的光通量进行了定量测定。用糖水训练自由飞行的蜜蜂选择其中一个彩色区域。然后改变照明方式，使得之前由训练区域发出的光通量现在在另一个区域测量。当在这些条件下对经过训练的蜜蜂进行测试时，它们仍然选择训练区域。改变彩色区域的相对位置以排除位置学习的影响。得出的结论是，在一定范围内，蜜蜂的色觉与照明的光谱成分无关。模型计算表明，在蜜蜂身上观察到的行为与视网膜理论（兰德，1977年）一致，即需要一种使用长程相互作用的算法来解释颜色恒常性。
