Rich Edomurasaki

#aa53ca
Notes

Rich Edomurasaki (#AA53CA) is a true violet with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (284°, 53%, 56%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. 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

Rich
adjective

Old French riche, wealthy, abundant — applied to color since the medieval period for hues that read as plentiful in pigment. Rich red, rich brown: the implication is depth combined with saturation, a color that gives the eye more to absorb. Sits at the saturated mid-light corner of the engine's grid, slightly warmer than bold and deeper than vivid.

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.
