A series of either thirteen or fifteen coloured test fields with hues from blue through grey to yellow were presented on a black background. Goldfish were trained on a bluish-grey test field by food reward. In the training situation, the setup with the coloured papers was illuminated with white light. In the test situation, the colour of the illumination was changed to blue or yellow. In both test illuminations the goldfish preferred the training field in the same way as under white illumination despite the fact that this test field stimulated the cone types very differently from the training situation. As test fields were present that excited the cones in exactly the same way as under white light, but were not chosen, colour constancy can be concluded. By means of colour metrics, it was possible to quantify direction and strength of colour constancy.
在黑色背景上呈现一系列由蓝色经灰色到黄色的13或15个彩色测试区域。通过食物奖励，让金鱼在蓝灰色测试区域接受训练。在训练场景中，带有彩色纸的装置用白光照明。在测试场景中，照明颜色变为蓝色或黄色。在两种测试照明条件下，尽管该测试区域刺激视锥细胞的方式与训练场景有很大不同，但金鱼对训练区域的偏好与白光照明下相同。由于存在与白光下以完全相同方式刺激视锥细胞但未被选中的测试区域，因此可以得出颜色恒常性的结论。通过颜色度量，可以量化颜色恒常性的方向和强度。
