On a glass board, which is "white"? I have a chess board made of frosted and clear glass pieces. The board is also comprised of alternating clear and frosted glass squares. I'm never sure how to orient the board. Which is the official "light colour" to put in the lower right corner?
At the lower right corner, the square's color should be White.  I have seen some glass chess boards and most of the times the frosted pieces/squares represent the Black side, and the clear pieces/squares the White side.
