Magisterial Plum
Magisterial Plum (#B65FE9) is a true indigo with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (278°, 76%, 64%) places it in the highly saturated band at a mid lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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
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.
Prunus domestica, the European plum cultivated since at least the time of Greek and Roman orchards. The color refers to the skin of a ripe Damson or Methley plum at peak ripeness: a deep, slightly red-shifted purple-blue with the slight bloom of waxy fruit surface. Cooler than mulberry, warmer than indigo, with the orchard weight of a fruit whose skin and flesh are different colors — and the skin is the namesake.
