I am mostly done with the Tzeentchian air force but need some input on painting choices. Below are the wip Firelords. I need a colour choice for the central “engine” area on top of the wing (the ripped surface). For the Slaneesh knights I used Scorpion Green followed by Thraka Green washes to create a green “power coil” look. The alternative for Tzeentch might be yellow with a red wash to create an orange power coil (to tie in with the yellow/orange accents of the rest of the Tzeentch force). Any suggestions?
