Sepulchral Quartz

#483418
Notes

Sepulchral Quartz (#483418) is a deep amber 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 (35°, 50%, 19%) 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 azure. 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.

Quartz
noun

Silicon dioxide — the most abundant single mineral on Earth's continental crust, occurring as everything from beach sand to gem-grade rock crystal. Quartz as a color refers to a polished pale-gray quartz crystal: a soft, very pale slightly cool gray with the high specular shine of a translucent silicate. Cooler than pearl, warmer than mist.
