Flavius Aetass posted:I was looking at a bright patch of a cloudy sky yesterday and it really stumped me. How can a bright area of the sky look simultaneously light yellow and light blue, but not green in any way? Does anyone else know what I'm talking about? We have red, blue, and green cones in our eyes, and big fat brains that make up a lot of poo poo to cover the gaps and contradictions those limited receptors send in. The sun shoots the full spectrum of white light at us during the day, and it interacts with atmospheric conditions to turn colors. Those conditions overwhelmingly favor either short waves -blues, or long wave- reds; the medium-greens are there, but they're being overwhelmed or combined with one of the others so you don't see green, just yellows or bright blues. Sometimes storms can alter the atmosphere to favor medium waves and you get green skys, but it's pretty rare.
