Yeah that one is pretty good. I still prefer anything but bright white for the light squares:
That's a handsome board, but I wouldn't own it because the dark squares are too dark IMO....however, I do tend to agree with your preference that the light squares be a little more of an off-white, rather than bright white hue.
My whole point is that the squares, both light and dark, should contrast well with both the light and the dark pieces....the pastels meet that requirement, are less strain on the eyes (when staring at a board for long periods), and are pleasant to look at...
