Pick something from https://lospec.com/palette-list
> where should i start?
one of those:
1. start with pencil and paper, and your computer turned off.
2. find some artist you and try to copy/steal from them; it's quite easy to copy something badly enough that it becomes semi-original : )
3. start making a game -> fail miserably -> grab bits and pieces and release because what else can you with all that graphics?
I usually go with 3, it's nice because you'll have semi complete set (which is like 100 times better then an incomplete one!)
