Ebon Udaipur

#1f1f55
Notes

Ebon Udaipur (#1F1F55) 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 (240°, 47%, 23%) 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 yellow. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Ebon
adjective

A poetic shortening of ebony — used principally in nineteenth-century verse and Edgar Allan Poe (The Ravenebon bird). As a color modifier, ebon is a literary register for deep black with slight warmth, distinct from the cooler inky and the harder jet. Carries the same weight as the wood it borrows from.

Udaipur
noun

The Rajput City of Lakes in Mewar, Rajasthan — home of the Mewar court whose miniature paintings used ultramarine (powdered Afghan lapis) and indigo for the deep skies and royal robes. Udaipur color refers to a Mewar-school 17th-century miniature's lapis-and-indigo sky field: a saturated, slightly cool deep blue-violet with the matte finish of mineral ultramarine on hand-prepared vasli paper.
