Subterranean Edamame

#304b01
Notes

Subterranean Edamame (#304B01) is a deep lime 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 (82°, 97%, 15%) places it in the highly saturated band at a dark lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. For a confident two-color system, pair it with its complementary indigo. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Subterranean
adjective

Latin sub-terraneus, under-ground. As a color modifier, subterranean implies the cool deep darkness of cave-and-tunnel interiors where ambient daylight has been completely eliminated. Sits at the deep-and-cool end of the grid, where the hue reads as cellar-dwelling rather than night-sky deep.

Edamame
noun

The Japanese name for fresh young soybeans (Glycine max) — boiled in salted water and served as a popular Japanese pub appetizer. The color refers to fresh-boiled edamame pods: a saturated, slightly cool yellow-green with the satin finish of cooked legume pod.

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.
