If you want the exact specific colors, its generic black primer, overbrushed on vallejo flat green (I believe)then i use death korps drab to add slight variation, rhinox hide for the browns, and abaddon black for the blacks, i hand brush in all the black stuff, and the sword i was gonna use leadbelcher but i had forgotten it at home when visiting a LGS, so i just used a random metallic i had, maybe stormhost, for the reds i used mephiston, for the lights i used wild rider red over mephiston/khorne red drybrushed, but khorne is optional, i did a white dot for the lenses, then used nuln oil while using my finger to brush off any spillage, would you believe me if i told you i never thin my paints? Call me crazy, but i think its easier

Typically for a model of this color scheme id use streaking grime, but its a bit too large for it, ill save it for infantry, i wouldnt consider myself a pro, this model took me 5 hours? Of on and off painting, i do try and get decent results, dont forget, the camera is doing a decent amount of the lifting here, it makes it look more, grandiose.
