Sepulchral Steller

#263a75
Notes

Sepulchral Steller (#263A75) is a deep blue with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (225°, 51%, 30%) 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 amber. 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.

Steller
noun

Cyanocitta stelleri, the Steller's jay — named for German naturalist Georg Wilhelm Steller, who collected the type specimen on the 1741 Bering Expedition. The males display saturated deep-blue plumage with black crests. The color refers to a male Steller's jay in fresh plumage: a saturated, slightly cool deep blue with the matte finish of structurally-colored corvid feathers.
