I really like Vallejo burnt red.
Vallejo black (super basic I know)
Vallejo German cammo dark green
Vallejo Metal Color gunmetal grey
Citidel Retributor armor.
These are just the ones I use a lot and enjoy using. I also really like ProAcryl for vivid base coats. Citidel paints are great for dry brushing. Don’t use contrast very often but recently discovered that I get really nice yellows by painting something skin tones and shading before finishing with one of citidel’s yellow contrast paints.
I’ve got plenty of unfinished good games to work on now. I’ll get it when it’s cheaper and a little more fleshed out.
