Buttressed Joy Royal

#2865e0
Notes

Buttressed Joy Royal (#2865E0) 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 (220°, 75%, 52%) 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

Buttressed
adjective

Old French bouterez, thrusting-mass — past-participle of buttress, derived from bouter (to thrust). As a color modifier, buttressed implies a saturated-and-architecturally-supported quality, the deep-rich color of Gothic-Cathedral flying-buttress-and-rib-vault stone-architecture. Sits at the bold-and-fortified end of the grid, parallel to fortified and reinforced.

Joy
modifier

Latin gaudia, delights. As a color modifier, joy implies a bright-and-radiant-and-uplifted quality, the visual register of Provençal-troubadour-and-Florentine-Carnival-joy hand-bright-and-radiant-and-uplifted Provençal-troubadour-and-Florentine-Carnival-and-Renaissance-festa joyful-and-bright-and-radiant-and-uplifted surfaces under Provençal-troubadour-and-Florentine-Carnival-and-Renaissance-festa banner-and-procession-and-piazza festival-day-light. Sits at the modifier-and-mood end of the grid, parallel to bliss and glee 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.

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.
