Resonant Ipomoea

#7d1b84
Notes

Resonant Ipomoea (#7D1B84) 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 (296°, 66%, 31%) 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

Resonant
adjective

Latin resonāns, echoing — present-participle of resonate, sharing root with sonance. As a color modifier, resonant implies a saturated-and-deep-vibrating quality where the hue carries low-frequency visual richness. Sits at the bold-and-resonant end of the grid, parallel to sonorous and resounding in usage.

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).
