仅当不同强度的光刺激视网膜上的邻近区域时，才能感知到不透明的消色差表面颜色。这些颜色是“相互作用过程的产物，取决于至少两个区域的刺激差异”。因此，暗场中的单个明亮区域被感知为发光的，而不是白色或灰色的表面颜色。”进行了实验，在暗室中观察到被不同强度的环包围的圆盘。”在这些情况下出现的颜色非常近似地取决于所涉及的强度的比率，并且似乎与局部刺激的绝对强度无关。较高强度的区域将呈现白色，而较低强度的区域将呈现灰色（或黑色），这取决于两个区域的强度比。“感知颜色对刺激强度比率的这种依赖性为不同照明下非彩色的恒定性提供了解释。在实验中通常无法获得完全恒定性的事实是由于两个以上不同区域之间的相互作用这一事实造成的。 涉及刺激强度。（PsycINFO数据库记录（c）2016 APA，保留所有权利）
Opaque achromatic surface colors are perceived only when light of different intensity stimulate adjacent areas on the retina. Such colors are" products of an interaction process, which depends on difference in stimulation in at least 2 areas." Thus, a single bright region in an otherwise dark field is perceived as luminous and not as a white or gray surface color." Experiments were conducted in which a circular disk surrounded by a ring of different intensity was observed in a dark room." The colors which come about under these circumstances depend in close approximation on the ratios of the intensities involved and seem independent of the absolute intensity of local stimulation. The region of higher intensity will assume the color white and that of lower intensity will show a gray (or a black) which depends on the intensity ratio of the 2 regions." This dependence of perceived colors on the ratios of stimulus intensities provides an explanation for the constancy of achromatic colors under varying illumination. The fact that complete constancy is usually not obtained in experiments is accounted for by the fact that interaction between more than 2 regions of different stimulus intensity is involved.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
