Pigments are the modeller's secret for the finest grime, and this faded green tone brings the muted colour of algae and tired vegetation. Use it for the greenish film that gathers on damp stonework, waterlines and neglected surfaces, or to tint groundwork with a mossy, overgrown cast.

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.
