Pigments are the modeller's secret for the finest dust, dirt and soil, and this sienna soil tone brings a warm reddish-brown earth to a scene. Use it for soil, dust and ground-in dirt with a warmer cast than a plain brown, ideal for terrain and the lower reaches of a vehicle.

Apply the fine powder dry for a dusty finish or fix it in place with pigment fixer or thinner, working over a matt surface for the best grip. Browse the full AK Interactive weathering effects range for more to build up alongside it.
