Somber Smithsonite
Somber Smithsonite (#07290D) is a deep green 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 (131°, 71%, 9%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. For a confident two-color system, pair it with its complementary magenta. 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.
A zinc carbonate mineral — named for English chemist James Smithson (founder of the Smithsonian Institution). The blue-green variety is mined principally in New Mexico's Magdalena Mountains. The color refers to a polished blue-green smithsonite cabochon: a soft, slightly cool deep blue-green with the satin finish of botryoidal zinc-carbonate mineral.
