Depending on the altitude and composition of the atmosphere, the glow can be of different colors and shapes. For example, if the solar wind collides with nitrogen, and as a result, it loses molecules, we will see a violet and blue glow, and if there is no loss of molecules, we will see all shades of red. The most common greenish glow is when oxygen molecules collide with the solar wind.
