Robust Aotearoa

#17630f
Notes

Robust Aotearoa (#17630F) is a deep 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 (114°, 74%, 22%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. 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

Robust
adjective

From the Latin robustus, of oak — implying strength combined with substance. As a color modifier, robust describes saturation combined with body: a robust burgundy, a robust olive. Sits in the bold-and-warm corner alongside strong and solid, with the slightly textural implication of a color that has substance behind the pigment.

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.
