Charred Ipomoea

#401c6e
Notes

Charred Ipomoea (#401C6E) is a deep 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 (266°, 59%, 27%) 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 lime. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Charred
adjective

The past participle of char, to burn slightly — and a color word for surfaces that have been heat-blackened without fully consuming. Charred implies the carbon-blackened skin of grilled meat, fired wood, or smoke-darkened cathedral stone. Sits in the deep-and-near-black end of the engine's grid, slightly drier than inky and warmer than somber.

Ipomoea
noun

Morning glory (Ipomoea purpurea) — a Central American Convolvulaceae annual cultivated worldwide for its trumpet-shaped deep-violet flowers that open at dawn and close by midday. Ipomoea color refers to a freshly opened Ipomoea purpurea trumpet at dawn: a saturated, slightly cool deep violet with the velvet finish of fresh fused-petaled trumpet corolla. The genus name combines Greek ips (worm) and hómoios (similar).

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.
