是否有必要用视网膜表示边缘来限制颜色填充的范围？如果是这样的话，那么颜色填充不应该受到虚幻轮廓的限制，因为它们不存在于视网膜水平。或者，如果颜色填充在神经表征的感知水平上受到轮廓的约束，则无论是否存在视网膜表征，颜色填充都应该受到虚幻轮廓的约束。为了解决这个问题，各种各样的真实的亮度边缘和虚幻的轮廓下，设计的条件下，导致颜色填充。结果表明，错觉轮廓限制了颜色填充的范围。轮廓的神经表征可能首先存在于视网膜水平或皮层水平;在任一情况下，轮廓存在于感知水平并限制颜色填充。
Is a retinal representation of an edge necessary to constrain the reach of color filling-in? If so, then color filling-in should not be constrained by illusory contours, because they do not exist at a retinal level. Alternatively, if color filling-in is constrained by contours at a perceptual level of neural representation, regardless of whether there is a retinal representation, then color filling-in should be constrained by illusory contours. To address this question, a variety of real luminance edges and illusory contours were presented under conditions designed to cause color filling-in. The results showed that illusory contours bounded the reach of color filling-in. A neural representation of a contour may first exist at a retinal level or a cortical level; in either case, the contour exists at a perceptual level and bounds color filling-in.
