RAL 230 40 10

Muted Hearth

RAL 230 40 10 Muted Hearth occupies hue 230, lightness 40, and a moderate chroma of 10, a subdued mid-dark true red that bridges crimson and warm grey like the cooling surface of a stone hearth after the fire has died. It is a natural choice for heritage structural elements, cinema interior millwork, and natural material colour coordination. The moderate saturation gives it a rugged, mineral quality that blends seamlessly with concrete, natural stone, and weathered timber.
