Gaudy Petrea

#b680ff
Notes

Gaudy Petrea (#B680FF) is a soft indigo 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 (266°, 100%, 75%) places it in the highly saturated band at a light 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 lime. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Gaudy
adjective

Middle English gaude, trick / showy ornament — adjectival suffix -y. As a color modifier, gaudy implies a saturated-and-cheaply-bright-and-overdone quality, the bright color of carnival-and-fairground novelty-attraction painted-and-lit decoration. Sits at the bright-and-flamboyant end of the grid, parallel to garish and lurid in usage.

Petrea
noun

South American purple wreath vine (Petrea volubilis) — a Caribbean and Central-American twining woody vine cultivated worldwide for its long pendulous racemes of deep-violet sandpaper-textured flowers. Petrea color refers to a fully bloomed Petrea volubilis pendulous raceme: a saturated, slightly cool deep violet with the matte finish of fresh five-pointed star-shaped sandpaper-textured corollas. Named for Robert James Petre, an English botanical patron of the 18th century.
