Aristocratic Robe Ruby

#a31626
Notes

Aristocratic Robe Ruby (#A31626) is a true 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 (353°, 76%, 36%) 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 teal. 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.

Robe
modifier

Old French robe, long-flowing-garment. As a color modifier, robe implies a long-flowing-and-academic-and-judicial quality, the visual register of Oxford-Cambridge-academic-and-judicial-robe hand-long-flowing-and-academic-and-judicial Oxford-Cambridge-academic-and-judicial-robe-and-monastic-habit robe-and-long-flowing-and-academic surfaces under Oxford-Cambridge-academic-and-judicial-robe-and-monastic-habit Senate-and-Inns-of-Court-and-cathedral-cloister Trinity-Senior-Common-Room-light. Sits at the modifier-and-textile end of the grid, parallel to gown and cope 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.
