Aristocratic Ube

#901b8a
Notes

Aristocratic Ube (#901B8A) is a deep violet 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 (303°, 68%, 34%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. For a confident two-color system, pair it with its complementary green. 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.

Ube
noun

Filipino purple yam (Dioscorea alata) — a tropical climbing vine cultivated for its deep-violet starchy tuber, the eponymous flavor-base for ube halaya jam, halo-halo shaved-ice dessert, and modern ube cake. Ube color refers to a freshly mashed Dioscorea alata tuber-flesh: a saturated, slightly cool deep violet with the matte finish of anthocyanin-rich starchy yam-pulp. The Tagalog name ube derives from the Cebuano ubi.

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.
