Not only that, depending on the time of day you will also see a different color. If you open Firefox in the evening, the browser will look slightly greenish. But in the middle of the afternoon, the colors will automatically turn to warm colors like gold or red, as if reflecting the sun's position in the sky (or air temperature).
This theme has no custom options but you don't need to do anything more. Quantum Lights turns the browser into an extremely flexible rainbow that does not affect browsing speed or machine speed.
