There are few white bricks around stormforge where you can get to stare directly at bright white brick (near the entrance to the palace and a couple of other places).
Secondly, the edge detection in gimp does a VERY impressive job of showing these off (use prewitt compass at full) and then you can use the curves (under colours menu) to enhance (pull the curve to the top near the beginning):
I've cut a small section of mine up so im not identifiable (i hope)
