Effulgent Edomurasaki
Effulgent Edomurasaki (#C778EE) 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 (280°, 78%, 70%) places it in the highly saturated band at a mid 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
Latin effulgēns, shining-out — present-participle of effulgere, sharing root with fulgor (lightning). As a color modifier, effulgent implies a saturated-and-radiating-light-out quality, the bright color of Renaissance-Madonna halo-and-aureole gold-leaf-and-pigment emission. Sits at the bright-and-saturated end of the grid, parallel to resplendent and radiant in usage.
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.
