Refulgent Iceland

#41aa17
Notes

Refulgent Iceland (#41AA17) is a true 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°, 76%, 38%) places it in the highly saturated band at a mid 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 violet. 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.

Iceland
noun

The North Atlantic island — and the saturated green of Icelandic mossy lava fields and the þúfur (hummocky) tussocks of Icelandic farmland. Iceland refers to an Icelandic moss-covered lava field: a saturated, slightly cool deep yellow-green with the slightly velvet matte finish of dense mossy undergrowth.
