Resonant Reed

#37821a
Notes

Resonant Reed (#37821A) is a deep green 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 (103°, 67%, 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 violet. 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.

Reed
noun

Phragmites australis, the wetland grass whose tall stalks and feathery seed plumes line freshwater margins worldwide. Reed color refers to a freshwater marsh dominated by phragmites in late summer: a soft, slightly cool yellow-green with the matte finish of upright wet-grass blade.
