Sepulchral Toucan

#511d08
Notes

Sepulchral Toucan (#511D08) is a deep orange 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 (17°, 82%, 17%) 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

Sepulchral
adjective

Latin sepulcrālis, of the burial-place — adjectival form of sepulcrum. As a color modifier, sepulchral implies the deep funereal-and-formal darkness of Holy-Sepulchre-and-rock-cut royal-tomb interiors of medieval-and-Renaissance Christendom. Sits at the deep-and-funereal end of the grid, parallel to entombed and funereal in tone, both literary and architectural.

Toucan
noun

The family Ramphastidae — tropical American birds with oversized colorful beaks. Toucan refers specifically to the keel-billed toucan (Ramphastos sulfuratus) whose beak is colored in green, yellow, orange, and red. The color refers to the orange section of a toucan's beak: a saturated, slightly red orange with the matte finish of keratin. Warmer than oriole.

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.
