Earnest Aotearoa

#21a03b
Notes

Earnest Aotearoa (#21A03B) 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 (132°, 66%, 38%) 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 magenta. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Earnest
adjective

Old English eornost, seriousness, zeal. Used as a color modifier since the nineteenth century for hues that read as committed but unshowy — the working blues of denim, the deep greens of Quaker meetinghouses. Sits in the bold-and-quiet corner of the grid, slightly less luminous than resolute and slightly less institutional than imperial.

Aotearoa
noun

The Māori name for New Zealand — the land of the long white cloud — and the saturated deep green of New Zealand's South Island fjordland and fern understory. Aotearoa refers to a Fiordland forest understory: a saturated, slightly cool deep yellow-green with the matte finish of Cyathea tree-fern foliage.

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.
