Authoritative Frangipani

#c33b9b
Notes

Authoritative Frangipani (#C33B9B) 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 (318°, 54%, 50%) 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.

Frangipani
noun

Caribbean and Polynesian Plumeria rubra — a tropical Apocynaceae tree cultivated worldwide for its highly fragrant five-petaled flowers in deep-magenta cultivars. The flowers are used in Hawaiian lei and Hindu garlands. Frangipani color refers to a freshly opened Plumeria rubra deep-magenta flower: a saturated, slightly cool deep magenta with the velvet finish of overlapping fleshy five-petaled corolla. Named for the Italian noble family that invented the perfume.

Display P3 representation

The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.

This color is chromatic enough that authoring it as P3 native (instead of clamping to sRGB) gives a perceptibly more saturated render on wide-gamut displays — modern Macs, iPhones, iPads, and most recent OLED laptops.
