Authoritative Sakurairo

#c52489
Notes

Authoritative Sakurairo (#C52489) is a true magenta with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (322°, 69%, 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

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.

Sakurairo
noun

Japanese 桜色, cherry-blossom color (Prunus serrulata) — the iconic pale-pink hanami color whose deep saturated form occurs in the yaezakura double-petaled cultivars. Sakurairo color refers to a yaezakura double-cherry petal at peak bloom: a saturated, slightly cool deep magenta with the velvet finish of fresh saturated double-petaled cherry-blossom. Warmer than kohbai and cooler than momo (peach).
