As long as the color is not one with a horrible contrast to the pieces, it shouldn't matter.
Same thing applies for over the board.
I can play on a board with Brown squares, Green squares, etc. But you start putting something like fire engine red, or hot pink, or Orange, or Neon Green, or anything that like and yes, it hurts the eyes!
I am curious if other player's expericene this also and why does this happen? I have been playing with classic pieces and a brown board for years online. If I change the board color or add a new theme it is like a deduction of 300 rating points.
