The Army Painter gives you another option for base-coating your minis with the release of Chaotic Red.
From the release:
A rich and very deep red colour that will fit perfectly as a basecoat for any red highlights. As the name suggests the Chaotic Red is a must have for Chaos miniature collectors of any system or as basecoat for futuristic warmachines or monsters. Suggested Quickshade is Dark Tone, but the versatile dark red colour can also stand on its own and be highlighted immediately after drying.
The new Colour Primer is available in all good hobby stores and direct from The Army Painter Webstore
