Authoritative Garance

#a21e61
Notes

Authoritative Garance (#A21E61) 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 (330°, 69%, 38%) 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.

Garance
noun

The French word for madderRubia tinctorum — and the dye that colored French military uniforms from the eighteenth century until garance was replaced by synthetic alizarin in 1869. The color refers to garance-dyed French wool: a saturated, slightly cool deep red with the matte finish of plant-and-mordant dye. The French equivalent of madder.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
