I also wouldn't tread in the waters of leaving the external 'bumpers' red or blue -- best to make them black or something neutral if the covers will never be changed. Sure, there's nowhere in the rules that states anything about the colors of external boundaries -- yet if the refs get confused about which alliance you're on ... well that part is a bit vague.
