Sepulchral Cardenal

#570b5e
Notes

Sepulchral Cardenal (#570B5E) is a deep violet 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 (295°, 79%, 21%) 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 green. 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.

Cardenal
noun

Spanish for cardinal — both the ecclesiastical office and the Lobelia cardinalis (cardinal flower) of New World gardens. The Spanish cardenal hat is technically deep red, but the color name slipped into Hispanic-American color terminology for the violet-tinted purples of cassocks. Cardenal color refers to a Spanish capa magna cardinal-cassock: a saturated, slightly cool deep violet with the matte finish of multi-bath ecclesiastical wool.

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.
