The armor is my favorite green so far, most reminiscent of some of my favorite minis from The Lost and the Damned galleries... all GW paints...
1. Castellan Green (Base)
2. Athonian Camoshade (Shade)
3. Straken Green (Layer)
4. Nurgling Green (Layer)
5. Carroburg Crimson (Shade)... wound and damage areas only
I'm having a hard time deciding which model(s) will actually BE champions and which ones will fall into ranks for a unit of Chaos Warriors. Maybe I need to have them fight it out on the table! I just picked up a few more on eBay...
