Don't rush to the obvious answer: "pale green." Yes, this is the most common color of the aurora, but other shades are possible.
The glow is caused by the collision of charged particles with atoms in the upper atmosphere. The color of the aurora depends on the specific particles colliding:
💚 pale green or scarlet – collisions of electrons with oxygen atoms
; 💜 violet – collisions of electrons with nitrogen atoms.
The color saturation and its warmth can vary depending on the aurora's altitude (the lower, the more intense) and external factors. For example, urban light pollution can turn green shades turquoise.
