Notes

Resonant Cardamom (#638823) is a deep lime 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 (82°, 59%, 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.

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.

Cardamom
noun

Elettaria cardamomum, the South Asian and East African spice whose green pods are essential to Indian chai, Scandinavian kardemumma baking, and Arab coffee. The color refers to fresh green cardamom pods: a saturated, slightly cool yellow-green with the matte finish of dry seed pods. Cooler than fennel.

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.
