Regal Glare Royal

#245fdc
Notes

Regal Glare Royal (#245FDC) 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 (221°, 72%, 50%) 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

Regal
adjective

Latin rēgālis, kingly — derived from rēx (king). As a color modifier, regal implies a saturated-and-royal-formality quality, the deep-rich color of British-Coronation-period royal vestment-and-mantle and Imperial-State-Crown regalia. Sits at the bold-and-imperial end of the grid, parallel to sovereign and royal in usage.

Glare
modifier

Middle English glaren, to-shine-brightly. As a color modifier, glare implies a harsh-and-bright-and-overwhelming quality, the visual register of desert-noon-and-snow-field-glare hand-harsh-and-bright-and-overwhelming desert-noon-and-snow-field-and-salt-flat glared-and-harsh-and-bright-and-overwhelming surfaces under desert-noon-and-snow-field-and-salt-flat overhead-sun-and-snow-blind-and-bleached harsh-noon-light. Sits at the modifier-and-mood end of the grid, parallel to flash and blaze 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.
