Bulky Clan Royal

#3b66db
Notes

Bulky Clan Royal (#3B66DB) 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 (224°, 69%, 55%) 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

Bulky
adjective

Old Norse búlki, cargo / mass — adjectival suffix -y. As a color modifier, bulky implies a saturated-and-massive-and-occupying quality where the hue takes up visual space with broad-and-heavy presence. Sits at the bold-and-weighty end of the grid, parallel to hefty and substantial in usage.

Clan
modifier

Scottish-Gaelic clann, children / family. As a color modifier, clan implies a Highland-Scottish-kinship quality, the visual register of Scottish-Highland-Clan Highland-and-Lowland hand-woven tartan-and-kilt-and-broadsword clan-and-kinship surfaces under Highland-Scottish-clan tartan-and-kilt-and-pipe-band Highland-pasture light. Sits at the modifier-and-cultural end of the grid, parallel to tribe and kin 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.
