Ebon Edomurasaki

#690575
Notes

Ebon Edomurasaki (#690575) 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 (294°, 92%, 24%) 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.

Edomurasaki
noun

Edo-period purple (江戸紫) — the deep blue-tinted purple popularized by Edo-period (1603–1867) Tokyo townsfolk and kabuki actors, distinguished from the warmer Kyoto kyō-murasaki. Edomurasaki color refers to a kabuki actor's Sukeroku role costume: a saturated, slightly cool deep violet with the silk luster of multi-bath gromwell-root dye on lined silk crepe. Cooler than Kyomurasaki.

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.
