ring around players mod??

Is there a mod to change the color of the ring around the players feet, for some reason mine is purple and i really would like to change it.

off the top of my head i dont know where that texture is located, but I know that if you press enter to get into the game, or if you press start on the controller, it changes which input device is "player 1" or "player 2" and will give them different colors.
