Authoritative Solferino
Authoritative Solferino (#B7368E) is a true magenta with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (319°, 54%, 46%) 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 auctōritāt-, authority — adjectival suffix -ive. As a color modifier, authoritative implies a saturated-and-formal-imperative quality where the hue carries decisional weight and institutional credibility. Sits at the bold-and-authoritative end of the grid, parallel to commanding and magisterial in usage.
Italian Lombardian town — site of the Battle of Solferino (June 24, 1859) which gave its name to a synthetic aniline magenta dye (the fuchsine-related solferino) developed in the 1860s. Solferino color refers to a solferino-dyed Second-Empire French silk faille: a saturated, slightly cool deep magenta with the silky luster of synthetic aniline dye on Lyon faille. Contemporary with mauveine and the Battle of Magenta's eponymous color.
