Please add for every team the possibility to choose an alternate shirt color. (Never allow primary and alternate color to match at team setup.)
I find it horrible when two purple team (so flashy) fight against one another ... and it's even worse if they are the same race.
Even in last world cup ... the final was Yellow against yellow ! sooo more difficult to spot players and enjoy the viewing.
Please, when colors are the same, make the hosting team play with his primary color and the opponent with his alternate color.
This is not much coding, just storing a second shirt color setup for each team.
