I’ve played 1 game and I’m already sick of the blue colour. If there’s no way of changing this, then I’ll definitely be requesting a refund (although probably won’t be able to get one)
If you play multiplayer you can avoid being blue most of the time. If you play with friends, you can play some other color every game.
If you only play offline against AI opponents then I can see your plight, however, it’s a tad overboard to be sick of a game because of your player color.
If you want to mix up the colour, turn on individual colours and play team games.
