Senatorial Edomurasaki

#81187d
Notes

Senatorial Edomurasaki (#81187D) 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 (302°, 69%, 30%) 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 green. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Senatorial
adjective

Latin senātōrius, of the senator — adjectival suffix. As a color modifier, senatorial implies a saturated-and-aristocratic-and-Roman-Republic quality, the deep-rich color of Roman-Senate toga praetexta purple-bordered ceremonial-citizen-class livery. Sits at the bold-and-aristocratic end of the grid, parallel to patrician and imperial.

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.
