I wish I had a finished bathroom to show you; but we are still puttering along with the tile. These were some pictures in my inspiration folder. I am starting to lean towards a light-greeny blue for the walls. The basic stuff is done. We've put black and white basket-weave tiles on the floor (which I love); it's the wall tile giving us trouble. We have to match to an existing tile to which there is no match, so I might end up going with a mosaic to get creative and blend everything. It becomes complicated when the original owners have tiled every wall 4 feet high.
I don't know the sources, but if I happen to show your bathroom, let me know!
