			I used the Dr. Colorship a few years ago, working on some quite small chips (smaller than match head-sized for the most part).  It's really easy and does a reasonably good job.  (If you look at all close,  you can still see them...but they are definitely better than before, especially since the primer---which is what was showing previously---is stark white.)  If you do a Search on "Dr Colorchip" and "Langka" (which I haven't tried), you'll get all kinds of hits.
