What are the "do's and dont's" when it comes to picking colors for the two players and the board in a 2 player abstract game? When you ask the players themselves, everyone has their own finicky preferences, with no real consensus between them. (Red & green might be the only way to go for player A, while player B hates red & green because he's colorblind.) Anyway, how do you come up with a colorscheme that pleases everyone - or what ones are already used that work?
If it's only for two players, you're in luck. Chess and Go are both over a thousand years old, and both use the classic combination of Black and White.
If you insist on having a colour, though, you want to follow black and white's example; have lots of contrast between them, and keep in mind accessibility. Amy's preference for red and green is far less important than Bill's colour-blindness when it comes to designing your game. Any dark colour and white will do this job, and this is commonly seen in chess sets; Red and White is common.
