Plentiful Uranus Ruby

#9a031d
Notes

Plentiful Uranus Ruby (#9A031D) is a deep red with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (350°, 96%, 31%) places it in the highly saturated band at a dark 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 teal. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Plentiful
adjective

Old French plentif, abundant — adjectival suffix -ful, derived from Latin plēnitās (fullness). As a color modifier, plentiful implies a saturated-and-generous quality where the hue carries rich visual abundance without restraint. Sits at the bold-and-saturated end of the grid, parallel to abundant and bountiful.

Uranus
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. Sits at the modifier-and-zodiac end of the grid, parallel to neptune and saturn in usage.

Ruby
noun

From the Latin ruber — simply, red. The gemstone is a chromium-tinged corundum, harder than anything in nature except diamond, and so saturated that a fine Burmese pigeon's blood ruby at auction outpaces a comparable diamond by weight. The color borrows the gem's confidence: a clear, glassy red without the brown of garnet or the blue of crimson.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
