RAL 090 30 40
Rich Malachite
RAL 090 30 40 Rich Malachite is positioned at hue 090, lightness 30, and chroma 40, a deep saturated cool green that evokes the banded mineral malachite and dense tropical canopy. It is specified for botanical garden structural elements, nature reserve signage, and luxury garden furniture finishes. The strong chroma at low lightness produces a colour of concentrated mineral energy and jewel-like depth.
