A long-wavelength background can affect the appearance of an increment of light superimposed upon it in two ways. It can change the visual system's sensitivity to the increment, and it can change the appearance of the increment by directly adding redness to it. Through selective retinal-image stabilization, we evoked the filling-in phenomenon to change the appearance of 640- and 575-nm backgrounds. Either of these backgrounds could be made to appear red or yellow, depending upon whether it was viewed under stabilized or unstabilized conditions. When the appearance of the 640-nm background was altered by filling-in to appear less red, test probes superimposed upon it required less 540-nm component to achieve an equilibrium hue. Increment thresholds measured on the 640- and 575-nm backgrounds, however, did not change with the appearance of the backgrounds.
长波长背景可以通过两种方式影响叠加在其上的光增量的外观。它可以改变视觉系统对该增量的敏感度，还可以通过直接给增量添加红色调的方式来改变其外观。通过选择性视网膜图像稳定，我们诱发了填充现象以改变640纳米和575纳米背景的外观。这两种背景中的任何一种都可以呈现红色或黄色，这取决于它是在稳定还是不稳定条件下被观察。当通过填充改变640纳米背景的外观使其看起来红色变淡时，叠加在其上的测试探针需要更少的540纳米成分来达到平衡色调。然而，在640纳米和575纳米背景上测得的增量阈值并没有随着背景外观的改变而变化。
