First thing to do is us primer paint on the base. Covering white paint is hard and so a dark, flat primer is good.
I used a light olive green for the upper piece, it matches the uniforms my soldiers usually wear, even this more khaki uniform looks okay with it.
The main part of the base is a very dark brown, it matches the boots very well. It also works well as a dirt color.
The vertical part of the base got a spray of the olive drab, a dark drab.
It also got a little over spray onto the base so it does not look so uniform.
Looks pretty good even close up. I am very happy withe the results. The paints are mostly Rust-Oleum Camouflage from Wal-Mat at about $4 per can.
