Authoritative Beaujolais

#a31b63
Notes

Authoritative Beaujolais (#A31B63) is a true magenta with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (328°, 72%, 37%) 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 teal. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Authoritative
adjective

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.

Beaujolais
noun

The French wine region just south of Burgundy — and the Gamay-based reds of Beaujolais Nouveau. The color refers to a fresh Beaujolais Nouveau in a glass: a saturated, slightly cool red with the optical brightness of low-tannin young wine. Lighter than Burgundy, brighter than Chianti.
