The color of the Aurora is determined by the altitude and density of the air and the energy emitted by molecules or atoms in the sky. When the excited atom reaches a certain altitude it is strong enough to split the nitrogen and the oxygen molecules thus shooting out the photons that create the auroras signature color. The colors are usually a variation of a red or green color. They can also range from red to pink, blue to purple and dark to light. The picture in the right shows how the atoms are creating different colors determining the altitude.
