I don't use the royal color scheme (purple + gold) much, but it's fun for abstract stuff. The generic altitude version would look more like this:

and the raw heightmap shading would look like this:

Those two aren't as much fun as the first one, but it's just playing with coloring at this point now that a heightmap is done.
