What causes us to see the colors differently and why does it happen?
In: Physics
A white sheet of paper looks white because it scatters all of the light that hits it. A red sheet of glass looks red because only red light passes through it.
So what if there was a kind of paper that only scatters blue light, but let red light through? If it was between you and a light, it’d look red, but you were on the same side as the light it would look blue. Our atmosphere is similar. It scatters blue and passes red, so the sky looks blue but the sun itself looks yellow or red. At a shallow enough angle, it passes through way more air, so it looks more red, to the point where even a bit of the scattered red light starts to stand out over the regular blue of the sky).
