What is the principle that the night scene at night is dominated by red?

Hello!

The colors of city lights are mostly red and orange, and bulbs of this color are used more in city lighting, so the color of night scenes is mostly red, especially in the sky. In fact, there is no pollution without city lights, and the sky should be dark blue.

I hope it will help you and I hope it will be adopted.
