Brimming Blaze Royal

#1663dc
Notes

Brimming Blaze Royal (#1663DC) 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°, 82%, 47%) 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

Brimming
adjective

Old English brymme, brim / edge — present-participle of brim. As a color modifier, brimming implies a saturated-and-overflowing quality where the hue spills past the edge of its visual container with rich pigmentation. Sits at the bold-and-saturated end of the grid, parallel to replete and abundant.

Blaze
modifier

Old English blæse, torch-or-flame. As a color modifier, blaze implies a roaring-and-bright-and-spreading-flame quality, the visual register of bonfire-and-Yule-log-blaze hand-roaring-and-bright-and-spreading-flame bonfire-and-Yule-log-and-hearth-fire blazed-and-roaring-and-bright-and-spreading surfaces under bonfire-and-Yule-log-and-hearth-fire roaring-and-bright-and-spreading midwinter-and-bonfire-night-light. Sits at the modifier-and-mood end of the grid, parallel to flare and spark 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.

Wide gamut

Display P3 representation

The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.

This color is chromatic enough that authoring it as P3 native (instead of clamping to sRGB) gives a perceptibly more saturated render on wide-gamut displays — modern Macs, iPhones, iPads, and most recent OLED laptops.
