We're talking all GW Citadel colors/colours
, right?
I think we have to relax a bit on the guidelines, the minis are supposed to reflect the painter's work afterall. That's kind of the point of doing a legacy team, you have to kind of expect the minis to be a bit different. Red Gore is a good base, but as far as technique goes I think it should be up to the individual.
Ok, then it is official:
Red Gore to go with the Skull White and Chaos Black. Highlight/shade as you see fit
