Magisterial Mojito

#42a111
Notes

Magisterial Mojito (#42A111) is a true green with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (100°, 81%, 35%) 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 violet. 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.

Mojito
noun

The Cuban cocktail of rum, lime, mint, sugar, and soda — popularized by Hemingway in Old Man and the Sea settings. Mojito color refers to a fresh-shaken mojito with crushed mint: a soft, slightly cool yellow-green with the optical clarity of muddled-herb-and-spirits.
