Flat Ube

#c6a3dd
Notes

Flat Ube (#C6A3DD) is a soft indigo with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (276°, 46%, 75%) places it in the balanced band at a light lightness. It works as a background wash, large-area fill, or soft illustration tone. Add a darker ink of the same hue when you need type over it. 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

Flat
adjective

Old Norse flatr, flat / level. As a color modifier, flat implies a clear-and-evenly-spread quality where the hue carries the matte-finish visual register of unmodulated single-plane surface. Sits at the crisp-and-balanced end of the grid, parallel to level and even in usage.

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.

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.
