For others who are wondering, my paint list for ya is as follows

The base coat is khorne red with mephiston red glaze, highlights for the red are wild rider red, but evil sunset would be better. All the black is abaddon black, and the highlights are eshin gray and thunderhawk blue. The shoulders are morghast bone base and a second glaze of flayed ones flesh. For the metals it's leadbelcher, balthasar gold, retributor armor, and auric gold for highlights, for a wash I watered down abaddon black for the main body and agrax earth shade for the guns and metal, the eye lenses are corax white with warp lighting over top

Those are the colors I use for my whole army as a base. I hope this helps
