Cimmerian Mahogany

#590812
Notes

Cimmerian Mahogany (#590812) is a deep red with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (353°, 84%, 19%) places it in the highly saturated band at a dark lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. For a confident two-color system, pair it with its complementary teal. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Cimmerian
adjective

From the Cimmerians of Homer's Odyssey — a legendary people who dwelled at the western edge of the world in perpetual darkness. As a color modifier, cimmerian implies a literary-poetic register for absolute darkness without sunlight. Sits at the deepest end of the grid, parallel to Stygian with classical literary connotations.

Mahogany
noun

The genus Swietenia — particularly S. macrophylla, the South and Central American hardwood prized since the eighteenth century for furniture and ship building. The color refers to a freshly polished Honduras mahogany table: a deep, slightly red-shifted dark brown with the satin finish of high-density tropical hardwood.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
