Magisterial Heather

#7d30b1
Notes

Magisterial Heather (#7D30B1) is a true indigo with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (276°, 57%, 44%) 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 lime. 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.

Heather
noun

Calluna vulgaris, the dominant ground cover of Scottish, Irish, and northern English moorland — the small woody shrub whose pink-purple flower spikes color hill country in late summer. The color refers to mature heather in August bloom: a soft, slightly muted pale purple-pink with the matte finish of small clustered flowers covering an entire moor at scale. Lighter than mauve, warmer than lavender, with the moorland weight of a plant whose name names a landscape.
