I just noticed that the skatesamples.com site now has the full board dimensions list pic as part of each board listing, which is good, as they didn't have that up before.
Not going to just post the pic here, but going to any of their deck listings, you can easily see, copy or save the image.

From what others have said, as well as boards I have from shops, the colours of top and bottom ply stains are totally random, so some might be pink bottom (or top) but the other colour could be anything, on top or bottom.
