Magisterial Saint Rose

#b00036
Notes

Magisterial Saint Rose (#B00036) is a true red 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 (342°, 100%, 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 teal. 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.

Saint
modifier

Latin sanctus, holy. As a color modifier, saint implies a hagiographic-and-relic quality, the visual register of Greek-Orthodox-and-Roman-Catholic-Saint hand-painted icon-and-relic-and-halo-and-iconostasis hagiographic surfaces under Greek-Orthodox-and-Roman-Catholic hand-painted icon-and-iconostasis hagiographic-tradition candlelight. Sits at the modifier-and-cultural end of the grid, parallel to monk and friar in usage.

Rose
noun

The Latin rosa, the Greek rhodon, the Persian gul — every European language has a different name for the same flower and the same color. Rose covers the spectrum from blush to fuchsia depending on the cultivar, but in pigment shorthand it means a cool, slightly bluish red — the inside of a damask petal, the dye that washes out of madder root.
