RAL 120 50 10

Dusty Harbour

RAL 120 50 10 Dusty Harbour is defined by hue 120, lightness 50, and a low chroma of 10, a muted earthy mid-tone that bridges cyan and cool grey. It is a natural choice for botanical-inspired interior schemes, natural fibre colour coordination, and wellness space surfaces. The restrained saturation gives it a sophisticated, mineral quality that pairs beautifully with raw timber, stone, and woven textiles.
