But the statement that sky is not blue on mars is not entirely true. The sky is blue because the molecules and atoms in the atmosphere scatter light from the sun.

White light, including sunlight, is made up of many different colors of light, each with its own corresponding wavelength. Anthony D. Del Genio of the NASA Goddard Institute for Space Studies and Columbia University explains.
