RAL 050 30 10
Smoky Bronze
RAL 050 30 10 Smoky Bronze occupies hue 050, lightness 30, and a restrained chroma of 10, a subdued dark brown-yellow that recalls patinated bronze and aged parchment. It is ideal for museum cabinetry linings, archive room shelving finishes, and traditional interior millwork. The very low chroma at this dark level gives it a near-neutral warmth that feels scholarly and distinguished.
