color schemes

[sen1van]

I think you can add color schemes (at least for android, on ios idk how to do this), it looks amazing to me

(sorry, how to change image size?)

If you have some code to create the color schemes, you can share it in a PR. What could be interesting also is a color scheme that would match the main color of the selected board.
Also how does it look like on the light theme?

actually to represent this idea, i just changed the colorSchemeSeed in app.dart, i tried to add a button in settings, but i don't have enough skills.

I see. I like the idea because the blue (which is lichess primary colour) is a little boring, especially in the light mode.
