For the blue base coat, I went with what is usually one of my second or third layers of dark blue and Ultramarine blue. I wanted this guy to be brighter than the rest of the Warriors (to make him seem less a part of the force, and more daemonic), so starting at a higher base coat helped with that. I also intended to get back to washes with him, which would require a lighter base coat.
I also did the base coat for the other not-metallic surfaces: Medium Grey for the hair and bone, and Stonewall Grey for the whites, prior to putting down the washes.
I believe I used three washes for this model: a blue (6:1 water to ink), a brown (8:1 water to ink), and a purple (10:1 water to ink). The purple ended up dominating the other two, but I didn't feel too badly about that, as I felt it would resonate with the dragon ogres in the army and some of the purple shading I'd done in other models.
First two layers of blue; ultramarine blue, followed by a mix of ultramarine and electric blue. I added a drop of turquiose to the latter layer to make it a bit odder in shade.
The next layer was a 50/50 mix of electric blue and turquoise.
Same colors, different proportion
Final two layers added white to the previous blue/turquoise layers
Though I had done both the mane and teeth/claws in medium grey, I decided to split them for layering ,as I wanted a yellowish mane for contrast. The claws/teeth are my typical Medium Grey/Bone White/White mixture, while the man started with Plague Brown and worked up to yellow.
After the bone and yellow was done, I mixed the stonewall grey with some wolf grey and started highlighting up towards white.
A brief interlude; the claws, skin, mane, and wraps are all done. All that's left is the blade, and the metal armor.
I decided to go with obsidian for his blade, so I researched the heck out of how its color works. In the end, I settled for a mixture of greys, SS camo black brown, purples, and black, with a lot of edge highlighting to make it look glossy without using gloss varnish.
For the armor, I went with a color scheme derived from pictures of lighters; that of metal that's been burnt. Rather than just light to dark, it goes light to dark to light, with some purple and browns mixed into the middle. I fear it's too subtle on this model (where there's a lot of other purple subtlety in the ink washes, which the armor just fades into), but it'll be something I probably try again in a scenario where it'll be more obvious.
A few final shots of the model, pre-basing. He never got used in a game, he just spend the whole event looking awesome. I'm OK with that!
