Reinforced Edamame

#509d21
Notes

Reinforced Edamame (#509D21) is a true 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 (97°, 65%, 37%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. 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

Reinforced
adjective

Latin re- plus inforce — past-participle of reinforce. As a color modifier, reinforced implies a saturated-and-doubled-up-and-strengthened quality where the hue carries layered pigmentation for maximum visual presence. Sits at the bold-and-fortified end of the grid, parallel to fortified and buttressed.

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.
