Vitreous Sandalwood

#81651e
Notes

Vitreous Sandalwood (#81651E) is a deep amber 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 (43°, 62%, 31%) 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

Vitreous
adjective

Latin vitreus, glass-like — derived from vitrum (glass). As a color modifier, vitreous implies a clear-and-glassy quality where the hue carries the optical clarity of polished crown-glass. Sits at the crisp-and-clear end of the grid, parallel to pellucid and crystalline in usage.

Sandalwood
noun

The genus Santalum — particularly S. album, the Indian sandalwood whose aromatic heartwood has been carved into Hindu and Buddhist religious objects since the Vedic period. The color refers to a freshly carved Mysore sandalwood Buddha: a soft, slightly cool warm tan with the satin finish of resin-rich wood.
