Acid Bermellón
Acid Bermellón (#F96A91) is a true red with a warm character. It leans warm, pulling light toward red, orange, and yellow. Naturally inviting, it suits editorial and hospitality contexts. Its HSL profile (344°, 92%, 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 teal. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Latin acidus, sour — sharing root with English acrid and acerbic. As a color modifier, acid implies a saturated-and-citric-and-zingy quality, the bright color of lemon-and-lime citrus-fruit-flesh and acid-yellow fluorescent-pigment surfaces. Sits at the bright-and-cool end of the grid, parallel to acidic and electric in usage.
Spanish for vermillion — the cinnabar-derived pigment used in the painted altarpieces of Castilian and Andalusian baroque. The color refers to a freshly mixed bermellón in a Sevillian polychrome workshop: a saturated, slightly orange red with the high gloss of pigment in oil. The Spanish equivalent of shu — different language, same mineral.
