What determines the colors? Particles from the Sun react with oxygen molecules to produce red or green light tones, while nitrogen molecules create blue and purple light tones. The pale yellow-green is the most common aurora color and is created by oxygen molecules located about 96 kilometers above the Earth. Rare red auroras are formed by oxygen molecules at 320 kilometers high.
