Aristocratic Pollux Royal

#3c6cdf
Notes

Aristocratic Pollux Royal (#3C6CDF) 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 (222°, 72%, 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

Aristocratic
adjective

Greek aristokratía, rule by the best — adjectival suffix -ic. As a color modifier, aristocratic implies a saturated-and-noble-and-hereditary quality, the deep-rich color of pre-modern European aristocracy hereditary-class livery-and-armorial-bearings. Sits at the bold-and-aristocratic end of the grid, parallel to patrician and lordly.

Pollux
modifier

Greek Πολυδεύκης, Gemini-twin-and-immortal-boxer. As a color modifier, pollux implies a Gemini-twin-and-immortal-brother quality, the visual register of Gemini-Pollux-and-Castor-twin hand-Gemini-twin-and-immortal-brother Gemini-Pollux-and-Castor-twin-and-Argonaut pollux-and-Gemini-twin-and-immortal-brother surfaces under Gemini-Pollux-and-Castor-twin-and-Argonaut spring-Gemini-and-Bortle-1-sky stellar-twin-light. Sits at the modifier-and-cosmic end of the grid, parallel to castor and spica 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.
