Authoritative Morganite

#a13281
Notes

Authoritative Morganite (#A13281) 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 (317°, 53%, 41%) 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

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.

Morganite
noun

Pink variety of the cyclosilicate beryl — first described from the San Piero in Campo deposits of Elba in 1911 and named for the financier J.P. Morgan. The color comes from manganese-and-cesium substitution. Morganite color refers to a faceted San Piero morganite gemstone: a saturated, slightly cool deep magenta with the glassy finish of cesium-and-manganese-substituted beryl. Cooler and pinker than aquamarine.
