Moss Green is AK Interactive’s gouache for damp, overgrown surfaces a cool, slightly murky green that reads as algae and moss rather than fresh paint. It’s water-based, so while it’s still wet on the model you can drag it, dab it or thin it further to control exactly how heavy the growth looks.

Best for

• Damp stonework, ruins and statues
• Algae streaks on hulls and boat waterlines
• Overgrown bases and forest terrain

Stipple it into recesses and corners first, where real moss actually gathers, then pull thin streaks downward with a damp brush for natural-looking run-off.

Matt, water-based gouache in a 20ml tube. Browse the full weathering effects range for more damp and organic tones to layer alongside it.
