For this one, a craft black paint (Americana Lamp Black), followed by Americana Light Cinnamon, Antique Gold and Vallejo Golden Yellow, all thinned so as not to create too much of a buildup on the model. I put a sliver of Americana White along one corner or lower edge and a dot or two of white in the middle of the black area for depth.
I find the craft paints tend to require less thinning in general and for shading work are still quite useful in getting a good effect.
