Brown is an excellent color that can do a lot for you. For starters, did you know that in the 1940s, only brown clothing was produced? That way, Americans could be constantly camouflaged, in case of enemy combatants. Of course, nowadays, we don't need brown that much... at least until the zombies arrive. Then you might want some camo.
