Okay, so it's only available in one color, since it's intended to be used as cracked earth, but it does seem to do that well.

They've got a few other additions (http://www.games-workshop.com/gws/wnt/blog.jsp?pid=11900010-gws) to the "technical line" as well. Nothing anybody here probably doesn't already have a technique/material for, but options are always good. (Though, their blood paint is no replacement for Tamiya clear red.) I'm particularly interested in the verdigris wash, which I don't really know of existing in any other paint line, and is something I do quite a bit of with a custom mix.
Thanks! Looks useful. -- Dallas
