Acidic Foulard
Acidic Foulard (#E665BB) is a true magenta with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (320°, 72%, 65%) 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
Latin acidus, sour — adjectival suffix -ic, sharing root with acetic and acerbic. As a color modifier, acidic implies a saturated-and-citric-and-sour quality, the bright color of lime-zest-and-pickled-lime citrus-fruit pulp surface. Sits at the bright-and-cool end of the grid, parallel to acid and electric in usage.
French foulard — a small lightweight square silk neckerchief, particularly the saturated-magenta foulard of Belle Époque French men's fashion (1870–1914). Foulard color refers to a Lyon-woven Belle-Époque silk foulard in a Maison Hermès showroom: a saturated, slightly cool deep magenta with the silk luster of multi-bath synthetic aniline dye on jacquard-figured Lyon silk.
