LutenantTan That's a really good point (and something I have to consider constantly in design work for my day job). It would be nice if there was a secondary design element to quickly identify a teammate (without having to memorize their name), like a geometric shape (circle, square, triangle, star) or icon of sorts.
I also wonder if teams could be grouped up and labeled in the locker room itself, so that in character select you are already next to your teammate(s) and there is some bracket or other (non color-based) representation that these 2-4 players are teamed up for this round.
