this is not clear who is who

When I joined the game, I do not know who is white, who is black.

Unless you are one of the players. Bottom player is always white.

I always forgot about that. We can write "WHITE" or "BLACK" watermark as background.
Like on the picture below, but bigger font and wider, so text fill from left to right.
