Two color-separation positive transparencies of a scene, one projected with "red" light and the other with tungsten lamp light, were superimposed on a screen. The light was polarized so that an observer wearing an appropriate viewer could either see both images in each eye or the "red" image in one eye and the "white" image in the other. These two situations gave different results, not the same results, as some previous investigators have claimed. Land's major results cannot be "obtained stereoscopically." We conclude that the process by which color is formed could possibly be a process of the retina or the lateral geniculate body, and does not necessarily have to be a process of the cerebral cortex as implied by the binocular experiments which purported to give the fuller gamut of color.
将一个场景的两张分色正透明片，一张用“红色”光投射，另一张用钨丝灯光投射，叠加在一个屏幕上。光线被偏振，这样佩戴合适观看设备的观察者既可以在每只眼睛中看到两个图像，也可以在一只眼睛中看到“红色”图像而在另一只眼睛中看到“白色”图像。这两种情况给出了不同的结果，并非如一些先前研究者所声称的相同结果。兰德的主要结果无法“通过立体视觉获得”。我们得出结论，颜色形成的过程可能是视网膜或外侧膝状体的过程，并不一定必须是如那些声称能给出更完整色域的双目实验所暗示的大脑皮层的过程。
