Color picker on the map

I've been wondering if it's possible to add a color picker on the map in game but a color picker i mean you can choose the color of your country you play. For instance Southern United States is usually red while Canada is green and France is blue. With the color picker you can assign yourself a desired color and any other country as well. This is not an essential tool but it might come in handy for some players. Right now i can't tell apart Egypt from Southern US in my 22 game.
