the sky is blue because of something called rayleigh effect, because our atmosphere is comprised of gas, (nitrogen mostly) when the light from the sun reaches it, the shorter wave length (cooler ends of the color spectrum.) are absorbed and refracted by the many molecules of gasses in the air, the color absorbed is the same color reflected, so when you look straight at the sun, you see white light, (which is really composed of every color) and when you look at the sky, you see the light reflected by our atmosphere. because the atmosphere is composed of primarily nitrogen, it reflects blue, oxygen i think is green, or greenish blue and carbon dioxide is red. when the sun sets, the light from the sun encounters even more gas molecules, going from bright white to yellow to orange to red, so when the sky looks red. it's because the longer wavelenth oranges and reds and warmer colors are now also being absorbed by the various gases in our atmosphere.
