In multi-player, Tag Coop mode : when you mouse over your custom color, the color goes a shade darker, but doesn't go back to normal after you remove your cursor. That implies that if you mouse over the color many times, it will go darker and darker until it eventually goes black. This has no effect on the colored discs in-game.
