Loud Petrea
Loud Petrea (#DD76C4) is a true magenta 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 (315°, 60%, 66%) 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
Old English hlūd, making noise — borrowed metaphorically as a color word since the nineteenth century. Loud red, loud yellow: a color so saturated it announces itself without needing surrounding context. Sits in the bright-bucket extreme alongside electric and striking. Carries a slightly pejorative implication of excess.
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.
