Cavernous Tanager

#5b0934
Notes

Cavernous Tanager (#5B0934) is a deep magenta 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 (329°, 82%, 20%) 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

Cavernous
adjective

An adjectival form of cavern, used principally for the deep darkness of large enclosed spaces. As a color modifier, cavernous implies the slightly cool deep blacks of a Lascaux-style cave or a basilica crypt — darkness with the optical complexity of a space larger than any single light source can fill. Sits in the deep-and-spatial end of the grid.

Tanager
noun

The genus Piranga — particularly P. olivacea, the scarlet tanager of North American summer forests, whose breeding-season males are vivid red with black wings. The color refers to a male scarlet tanager at full breeding plumage: a saturated, slightly cool bright red with the matte finish of carotenoid-pigmented feathers. Brighter than cardinal, warmer than crimson.
