I thought this was the Red Keshik color scheme but it isn't really. Still, I think these look good and it was fun playing with Army Painter Speedpaints. I think they work really well on mechs and I probably spent more time waiting for them to dry than I did actually painting.
White primer and then Army Painter Speedpaint 2.0 Slaughter Red and Gravelord Grey for the armor.
Lenses were VGC Dead White, GW Contrast Talasar Blue, VMC Deep Sky Blue, and VGC Dead White.
Lasers were GW Flash Gitz Yellow and VGC Dead White.
Metals were Vallejo Metal Color Duraliminium and the new formula GW Nuln Oil.
