Brimming Hera Royal

#3563ea
Notes

Brimming Hera Royal (#3563EA) is a true blue with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (225°, 81%, 56%) 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.

Hera
modifier

Greek Ἥρα, queen-of-the-Olympian-gods. As a color modifier, hera implies a peacock-feather-and-queen-of-gods quality, the visual register of Olympian-Hera-and-Argos-temple hand-peacock-feather-and-queen-of-gods Olympian-Hera-and-Argos-temple-and-Heraion-of-Samos hera-and-peacock-feather-and-queen-of-gods surfaces under Olympian-Hera-and-Argos-temple-and-Heraion-of-Samos Polyclitus-and-Argive-and-Samian peacock-throne-light. Sits at the modifier-and-myth end of the grid, parallel to zeus and diana 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.
