He's primarily Warlock Purple, drybrushed with a mixture of Warlock Purple and Skull White. The "wings" on his costume are Warlock Purple mixed with Chaos Black. His crown, belt, and the end of his staff are Dwarf Bronze. The decorations on the front of his robes are Golden Yellow, with some detail work around the "sunburst" a mix of that and Chaos Black. The base is Dark Angels Green and flocked with brown flocking.
I used this mini to represent Dars, an important NPC wizard in the city of Manifest (Ghostwalk).
