Thank you all for your comments and suggestions... "Congo" (along with German expedition) has arrived from North Star and I am slowly building my forces...
I also ordered "The Men Who Would Be Kings" and I am currently eyeing "The Heart of Darkness" on the bookshelf... It looks I have gone fully native!
Speaking of natives, I also have Congo tribes (former cannibals) to paint, as could be seen from above picture... I have a following question - do you have a dark African flesh triad (similar to Foundry's) to recommend? I have their African flesh triad, and it is a nice dark chocolate color, but I want my natives to be darker, mostly to differentiate them from the Africans in the European explorers service. I can always add a little black to that triad, but if anyone knows good recipe for dark African flesh that involves Vallejo colors (most of my paints are theirs)... I am listening...
