Authoritative Punch

#c0338c
Notes

Authoritative Punch (#C0338C) is a true magenta with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (322°, 58%, 48%) 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.

Punch
noun

A bright pink-red color named for the surface of a fruit punch — particularly the Tahitian-style punches of mid-century cocktail culture and the brand-name Hawaiian Punch whose color was a signature. The color refers to a saturated, slightly cool red-pink: brighter than fuchsia, warmer than rose, with the mid-century-tropical weight of a color tied to a specific decade of American cookout entertaining.
