I'm taking the color scheme straight from the first edition Monster Manual: dark brown skin, orange clothing, etc. So far that's about all I have blocked out, and I haven't painted any of the smaller features on this figure or done any highlighting or washes.
I decided to test the package's claim that its ready for painting, no priming required. It seems to be more or less true; the paint did seem to go on a little thin at times, but that just may be the craft store paints I'm using. I will share some more photos once I finish this mini later in the week.
