颜色的奥秘

长期以来,我们在享受着五彩缤纷世界的同时,也在探究这样的问题:什么是颜色?人类如何感知颜色?我们的祖先是否也能感知同样奇妙的色彩?

Dichromatic humans--who lack either L or M cones--are unable to experience the lush diversity of hues in fall leaves. But dichromaticity has advantages, too. It appears to confer an improved ability to distinguish textures and to spot camouflage. During the Second World War, the British Royal Air Force used color-blind dichromats to spot camouflaged camps and vehicles in reconnaissance flights over enemy lines.
