Refulgent Bamboo

#b4dd5e
Notes

Refulgent Bamboo (#B4DD5E) is a true lime with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (79°, 65%, 62%) 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

Refulgent
adjective

Latin refulgēns, shining-back — present-participle of refulgere, sharing root with fulgor (lightning). As a color modifier, refulgent implies a saturated-and-reflective-shining quality, the bright color of polished-bronze-and-armor reflective-surface mid-day-sun reflection. Sits at the bright-and-saturated end of the grid, parallel to effulgent and resplendent in usage.

Bamboo
noun

The subfamily Bambusoideae — fast-growing tropical and temperate grasses essential to East Asian architecture, scaffolding, and cuisine. Bamboo color refers to fresh bamboo culms in a Kyoto garden: a saturated, slightly cool yellow-green with the satin finish of segmented culm. Cooler than yamabuki.

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.
