I don't play the game, but my dad and some users at work that are colorblind. They set the colors to stuff that are very odd looking to normal eyes, but to them it looks good. One user is red/green colorblind and he eliminates the colors where ever he can. So a lot of blues and blacks.
so if the game uses a lot of red/green in color pallet, they would change it shades of blue purple something that red/green colorblind people can see without issue.
