The sky appears blue because when sunlight hits nitrogen and oxygen atoms in the atmosphere, photons are absorbed by electrons, over-energizing them and causing them to emit newly created photons; since blue light is more densely packed with photons than other colors, the atmosphere absorbs and emits more blue light, making it the dominant color we observe.
