When playing in an arena game, especially in Knockout, your starting color is (from what I’ve seen) based on your last chosen color. However, if someone is already with that color, it gives you a random color instead, which you can’t change in Knockout. So I think that instead there should be an option in your profile to list all the colors you have from your favorite to the least favorite, and if your favorite color is taken, it will move to the second, then third and so on. That way, you will have a color you don’t like much less often. It isn’t too important but it is annoying sometimes when you get a color you don’t like in Knockout and can’t change that.
