Warhammer 40,000 – I just wrapped up a group of three Hell Drakes for my Chaos Cultist Client. He wanted them to match the rest of his force with a basic three color plus wash level of detail. When I got these from him they were assembled and primed with a light coat of paint.
The models were pretty straight-forward to paint up using a red base, brass edging and some bone color for the talons. After a quick wash they were just about done. To make telling them apart easier on the tabletop I painted the eyes and bale flamer different colors on each. It's really subtle but if he needs to he'll be able to differentiate them. In 40K you use tokens more often than not that are placed on the model.
