RAL 300 40 05

Muted Garden Stone

RAL 300 40 05 Muted Garden Stone occupies hue 300, lightness 40, and a minimal chroma of 05, a near-neutral mid-dark tone that barely hints at lime green beneath its grey surface, like the blush of moss on weathered garden flagstone. It is a natural choice for heritage structural elements, contemporary office wall surfaces, and natural material colour coordination. The very restrained saturation gives it a timeless, architectural quality that blends seamlessly with natural stone and aged timber.
