Somber Bixa
Somber Bixa (#821A11) 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 (5°, 77%, 29%) 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 cyan. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
From the French sombre, dark, gloomy — itself from the Latin sub umbra, under shadow. Used as a color word since the eighteenth century to imply restrained darkness — the deep grays and blue-blacks of mourning dress and Victorian parlor decoration. Sits in the deep-and-quiet end of the grid, closer to brooding than to charred.
Bixa orellana, the proper genus name of the annatto shrub — the South American plant whose seed pulp gives the red food coloring of Latin American cuisine and the body paint of indigenous Amazonian peoples. The color refers to fresh bixa pulp: a saturated, slightly orange red with the matte finish of plant pulp. Warmer than annatto, deeper than tangerine.
