Thanks for the opinions, people. I tried to get that sort of deep bronze tan, in daylight it isn't really all too red. I think I would paint white skin the same way, if I wanted to get the tanned look. I think I will vary the colour a bit on individual figs, so some will look darker and some lighter.
The base colour was Cavalry Brown (VA MC) mixed with a bit of Dwarf Flesh (VA GC).
