RAL 020 30 15
Smoky Umber
RAL 020 30 15 Smoky Umber occupies hue 020, lightness 30, and a restrained chroma of 15, a subdued dark red-orange that recalls smoked leather and aged brick. It is ideal for heritage brickwork colour coordination, bookshelf joinery details, and traditional pub interior panelling. The low chroma at this dark level gives it an earthy, grounded quality that feels authentically aged.
