Dressed Tartarus
Dressed Tartarus (#16052E) is a deep indigo 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 (265°, 80%, 10%) 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 lime. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Old French dresser, to arrange — past-participle of dress. As a color modifier, dressed implies a neutral-and-arranged-and-formal quality, the neutral color of Edwardian-period full-formal-and-evening-wear arranged-and-coordinated dress-attire-and-uniform craft-finish. Sits at the neutral-and-traditional end of the grid, parallel to suited and tailored in usage.
Greek Τάρταρος, the deepest pit — the abyss beneath Hades itself where Zeus imprisoned the Titans after the Titanomachy. Tartarus color refers to the deepest cave of an Attic 5th-century BCE katabasis vase-painting: a saturated, slightly cool deep black with the matte finish of carbon-and-iron-tannin pigment on red-figure-style fired Attic ceramic. The deepest stratum of the Greek underworld cosmology.
