Fortified Squire Royal

#2370ec
Notes

Fortified Squire Royal (#2370EC) is a true azure with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (217°, 84%, 53%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Fortified
adjective

Latin fortificāre, to make strong — past-participle of fortify. As a color modifier, fortified implies a saturated-and-strengthened-and-defensive quality, the deep-rich color of Vauban-style military-fortification stone-and-earth rampart-and-bastion architecture. Sits at the bold-and-fortified end of the grid, parallel to bastioned and armored.

Squire
modifier

Old French escuyer, shield-bearer. As a color modifier, squire implies a knight's-attendant-and-page-of-arms quality, the visual register of English-and-French-Squire hand-forged shield-and-stirrup-and-tabard knight's-attendant-and-page-of-arms surfaces under English-and-French-Squire hand-forged shield-and-stirrup ceremonial-court light. Sits at the modifier-and-cultural end of the grid, parallel to knight and page in usage.

Royal
noun

The blue of European royal court dress and regalia from the late seventeenth century forward — the color of British peers' robes, French royal sashes, the lining of the crown-jewel cases. The color refers to a saturated, slightly violet-shifted blue with the matte finish of velvet or melton wool dyed to maximum intensity: deeper than cornflower, warmer than ultramarine, with the heraldic weight of a color reserved for monarchs and the official Crown.
