When one sits down to draw the sun, every child knows to use the yellow crayon, right? Well, sort of. As the video below explains, the sun actually gives off more visible light that’s green than any other color. But as is explained, color is not something that exists in the world, rather it’s something internal that we perceive. Between the filtering effects of the earth’s atmosphere and the way our eyes have evolved to perceive light, the sun appears as some mix of white, yellow, and red. Even if it’s really green.
