Majestic Glaucophane

#2148a0
Notes

Majestic Glaucophane (#2148A0) is a true azure 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 (222°, 66%, 38%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Majestic
adjective

Latin māiestātis, majesty — adjectival suffix -ic. As a color modifier, majestic implies a saturated-and-imposing-grandeur quality, the deep-rich color of Salisbury-Cathedral-and-Chartres-Cathedral Gothic-architecture monumental presence against the open sky. Sits at the bold-and-imposing end of the grid, parallel to regal and imperial.

Glaucophane
noun

A sodium-aluminum amphibole mineral — the principal blue component of blueschist metamorphic rocks. Mined principally in California, Greece, and Italy. The color refers to a polished glaucophane crystal: a saturated, slightly cool deep blue with the satin finish of fibrous amphibole. Cooler than dumortierite.
