Yeah, just another case of not thinking things through. "Say, I know, we'll show everyone how pure and American we are by using the colors of the flag to identify sections of the arena. Can't be more American than Old Glory,.... the Red, White and Blue.
Unforeseen problem: Stand alone, no one sees "White" and automatically connects that with "Red, White and Blue". Republicans see "Red Seating Area" and some are going to thing, "Ah, that's like "red states". Good, conservative. Others, of the John Birch ilk are quite likely to see "Red Seating" and want to go root out the commies. Who in the GOP, running for elected office, is going to want to go to the Blue area?
