Sky Blue

The blue color of the sky is caused by the scattering of sunlight off the molecules in the atmosphere. This scattering, called Rayleigh scattering, is more effective at short wavelengths - the blue end of the light spectrum. The blue of the sky is more saturated when you look further away from the sun.
