Grim Ube

#57007b
Notes

Grim Ube (#57007B) 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 (282°, 100%, 24%) 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 green. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Grim
adjective

Old English grimm, fierce / fierce-faced — sharing root with German grimm and Old Norse grimmr. As a color modifier, grim implies a deep-and-cool-and-comfortless-formal quality, the dark cool-gray of Norwegian-fjord mid-winter atmospheric-overcast light. Sits at the deep-and-cool end of the grid, parallel to bleak and stern in atmospheric register.

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.
