Pure User Text
I've found many user text colors, particularly Pure, but also Pharos, Aurora, and probably a couple other similar ones, to be extremely annoying. Seeing your opponents points is an extremely important part of the game, and taking this away makes it much more difficult to decide how to play. Do you try to dq them or aim for more points?
Yes, you can zoom in really close to see them, but that's not the point. That takes time, which is still a handicap. Therefore, I suggest giving a dark highlight to these text colors. Just a thin outline around each letter or number so that the text can still be the given color, but also be readable. This would end a huge amount of grief that I, and I'm sure others as well, have run into with playing against people who use these text colors.
