The way I've done mine -
Caliban Green, Biel-Tan Green, Warpstone Glow, Moot Green and way watcher green as a glaze - for the regular troops
Zandri Dust, seraphim sepia, ushabti bone, screaming skull and praxeti white - For the Deathwing, but you can find different tutorials online to paint those
I painted my chaos a different look from the cover
