Vivid Iceland

#63b43f
Notes

Vivid Iceland (#63B43F) is a true green with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (102°, 48%, 48%) 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 violet. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Vivid
adjective

From the Latin vividus, full of life — used as a color modifier since the late sixteenth century for hues that read as luminous and saturated. Vivid red, vivid blue: the implication is that the color appears almost lit from within, with the optical brightness of a high-chroma surface in good light. Sits at the bright-bucket center alongside bright and electric.

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.

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.
