Authoritative Taro

#7c3ba3
Notes

Authoritative Taro (#7C3BA3) is a true indigo 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 (278°, 47%, 44%) 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 lime. 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.

Taro
noun

Asian-Pacific Colocasia esculenta — a tropical Araceae root crop cultivated for its starchy corm, with deep-violet purple-flesh cultivars (the bun long and Lehua maoli taro) used for poi and ube-style purple desserts. Taro color refers to a freshly cut Colocasia esculenta purple-flesh corm: a saturated, slightly cool deep violet with the matte finish of anthocyanin-rich starchy taro-pulp. The Polynesian name taro spread to English.
