Step-by-step for painting him in here:
I primed with gray and then a zenithal spray of white. It doesn't show up in the pics very clearly, but this does provide some nice contrast and a guideline for later shading and highlights.
We're blocking, we're blocking, we're washing. The yellow is blocked with my I.F. yellow mix, and the black is a 1:1 mix of Chaos Black and Fenris Grey. I apologize for calling out old paints, but I have a lot to use up! The red is a 1:1 mix of Blood and Dark Flesh, the gray is Codex, and the skin is Tallarn. The yellow then receives a wash of Bestial Brown while the gray gets Badab. Red gets good ol' Devlan Mud, and Ogryn over the Tallarn.
Okay, you caught me, this isn't really much of a step-by-step. I lost track of the camera work once I began bringing colors back up and highlighting. I also apologize for the myriad lighting setups...the background is the same in all the pics.
