the four colour theory states that in a map, you will never need more than four colours, and in that figure, there will never be two same colours sharing the same border!
i've tried it myself! and amazingly IT WORKED!!
my 4 colours are green, red ,yellow and blue!
HAHAs. ok, maybe i'm a little too free (:
