Add palette color support

[Veykril]

I just thought it might be of interest to start a discussion about this. I noticed this crate uses it's own simplistic color definitions, so to my mind came the possibility of using the palette crate which would allow users to define and use colors in a very great spectrum.

Yes, that looks awesome. Thank you for this suggestion.

I wouldn't mind making a PR for this as well then.
