Patrician Venus Ultramarine

#306ffe
Notes

Patrician Venus Ultramarine (#306FFE) is a true azure with a neon character. It sits at the high-saturation edge of its family. Use it sparingly, as signage, accent, or highlight against darker surfaces. Its HSL profile (222°, 99%, 59%) 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

Patrician
adjective

Latin patrīcius, of the noble class — derived from pater (father). As a color modifier, patrician implies a saturated-and-aristocratic-and-Roman-Republic quality, the deep-rich color of Roman-Patrician-class toga and senatorial-livery hereditary-aristocratic dress. Sits at the bold-and-aristocratic end of the grid, parallel to senatorial and imperial.

Venus
modifier

Latin Venus, Roman-goddess-and-second-planet. As a color modifier, venus implies a Roman-goddess-and-second-planet-and-morning-evening-star quality, the visual register of Botticelli-Birth-of-Venus-and-Pompeii-fresco hand-Roman-goddess-and-second-planet-and-morning-evening-star Botticelli-Birth-of-Venus-and-Pompeii-fresco-and-Aphrodite-Hellenic venus-and-Roman-goddess-and-second-planet surfaces under Botticelli-Birth-of-Venus-and-Pompeii-fresco-and-Aphrodite-Hellenic Florentine-and-Pompeian dawn-and-dusk-evening-star-light. Sits at the modifier-and-zodiac end of the grid, parallel to jupiter and saturn in usage.

Ultramarine
noun

The pigment ground from lapis lazuli — the Afghan mineral imported through Venice in the late Middle Ages, more expensive by weight than gold during the Renaissance. The color refers to a freshly mixed ultramarine pigment in linseed oil: a saturated, slightly violet-shifted deep blue with the matte finish of micron-ground rock. Deeper than cobalt, cooler than royal, with the art-historical weight of the blue Vermeer reserved for Mary's robe.

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.
