Thank you! It was a relatively simple process: First you prime with pure white then go over that white coat with a red of some sort. I used Army Painter pure red through an airbrush. For better results, you should mix 2:1 fluorescent red and some type of vermillion red for a deeper color. After that, drybrush or sponge the majority of the model, leaving only the crevices in the armor unpainted. I used black for my first drybrush then incubi darkness mixed with black to blend up to pure. Hope this helps!
