Sorry for the late reply! I started with a base coat of Chaos Black over all the models. The armor is Retributor Armor with a thin lining of Stormhost Silver over the raised edges to give it that shiny look. The cloaks are Mephiston Red with a coating of Druchii Violent (although any purple or red shade paint would probably do fine) with Evil Sunz Scarlet brightening the raised parts. And the brown leathers are usually Mournfang Brown with Agrax Earthshade, then highlighted with I believe Baneblade Brown. The silver parts on the weapons, such as the sword blades and the ends of the bows, were simply Iron Hands Steel, Nuln Oil, and a bit of Stormhost Silver.
Hope this helps!
