Magisterial Frangipani

#b21b78
Notes

Magisterial Frangipani (#B21B78) 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 (323°, 74%, 40%) 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

Magisterial
adjective

Latin magisterium, teacher's office — adjectival suffix -al. As a color modifier, magisterial implies a saturated-and-authoritative-and-formal quality, the deep-rich color of Qing-dynasty civil-magistrate court-and-ritual textiles and Imperial-Examination scholar-class livery. Sits at the bold-and-authoritative end of the grid, parallel to authoritative and commanding.

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.
