Sorry, another beginner question. I have not heard of any method of shading that makes sense, except for this one. I found it on another web site and wondered if it is a good idea.
Wash the figure
Paint all upper surfaces white
Paint all lower surfaces black
cover with actual color (i.e. olive drab)
By upper and surfaces, it means the top of a curve, the part you would see from above the figure, and viced versa for the lower surfaces.
Any feedback/suggestions are greatly appreciated, I'm just trying to make sense of proper figure painting.
