Ebon Hashita

#510750
Notes

Ebon Hashita (#510750) 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 (301°, 84%, 17%) 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

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.

Hashita
noun

Japanese 半色, half-color — the technical Heian-court term for any kasane layer combination yielding a specific hue rather than a primary one. Hashita color refers to a Heian-period hashita-iro combination of a single-bath gromwell-and-indigo: a saturated, slightly cool deep violet with the silk luster of layered single-bath natural dye on hand-spun silk crepe.

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.
