For the 6 miniatures I used some combination of the following colors for the paints and shirts. Trying to make then distinct. For the hats I just picked one of the colors also.
"Khaky" (I tried to mix my own khaky color, it didn't work it end up a bit to green, but here is the receipt): ( Orange Fire 3:1 Magic Blue ) :1 Dead White
Blue using Magic Blue
Brown using Flat Earth
Grey using Cold Grey
