Adapt the color of the last move's accentuation to the color of the board

The accentuation of the last move is very helpful, but, it is g r e e n. Always g r e e n. Playing on a board with a different color scheme is, at least for me, impossible: Looking at a, say, blue and white board with two greenish spots distracts me in a way I simply must switch to the green and white board.
