Later. . .
It occurs to me that I might use the Speedball red ink as a shadow color (between torsos and arms) on top of the Winsor & Newton Alkyd Cadmium red. This is a bit more subtle than black lining, but I'll continue to use black lining against the white areas. Oh, and the shadow color on the figures' faces is from an old battle of Ral Partha "Leather."
