Authoritative Uranus Violet

#804ade
Notes

Authoritative Uranus Violet (#804ADE) is a true indigo with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (262°, 69%, 58%) 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 lime. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Authoritative
adjective

Latin auctōritāt-, authority — adjectival suffix -ive. As a color modifier, authoritative implies a saturated-and-formal-imperative quality where the hue carries decisional weight and institutional credibility.

modifier

Greek Οὐρανός, primeval-sky-god-and-seventh-planet. As a color modifier, uranus implies a primeval-sky-god-and-pale-cyan-seventh-planet quality, the visual register of Greek-Uranus-and-Herschel-discovery hand-primeval-sky-god-and-pale-cyan-seventh-planet Greek-Uranus-and-Herschel-discovery-and-tilted-axis uranus-and-primeval-sky-god surfaces under Greek-Uranus-and-Herschel-discovery-and-tilted-axis 1781-Slough-discovery-and-side-rolling-planet pale-cyan-planet-light.

Violet
noun

Viola odorata, the European sweet violet — small, fragrant, and the original meaning of the color name in English (the Violet of the rainbow). The color refers to a fresh sweet violet blossom in late winter: a saturated, slightly red-shifted deep blue-purple with the matte finish of small five-petaled flower. Cooler than amethyst, warmer than indigo, with the perfumed weight of a flower used in Roman garlands and Victorian eau de toilette.
