Would love to help you, but I'm using Vallejo Model Color paints...

While in the end I went with a 28mm metal range for my F&IW Wargaming (for which the painting is more complex), I did speed paint some Italeri Woodland Indians years ago. I used only Vallejo Leather Brown primer, followed with a wash. The figures turned out quite OK, but would need at least one highlight... well, it was the simplest way.

An example:

The best suggestion would be to use the paint guide on the back of the Italeri AWI Indian Warriors set #6061 as they just might be in the same region and only 30 years apart. At least that way you will have the "correct" paints.
