RAL 310 35 10

Smoky Moss

RAL 310 35 10 Smoky Moss is defined by hue 310, lightness 35, and a moderate chroma of 10, a muted dark green-yellow that carries the dusky warmth of dried moss on old stone walls and the quiet interior of aged potting sheds. It is a natural choice for heritage garden wall finishes, artisan workshop wall surfaces, and natural material colour coordination. The moderate saturation at this dark level gives it a grounded, organic quality that pairs well with terracotta, aged oak, and natural stone.
