Rugged Pine

#177d24
Notes

Rugged Pine (#177D24) 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 (128°, 69%, 29%) 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

Rugged
adjective

Old Norse rugga, rough / coarse — adjectival suffix -ed. As a color modifier, rugged implies a saturated-and-rough-and-weathered quality, the deep-rich color of Scottish-Highlands-and-Norwegian-fjord outdoor-and-mountain landscape. Sits at the bold-and-weathered end of the grid, parallel to tough and sinewy in usage.

Pine
noun

The genus Pinus, conifers spread across nearly every continent — white, ponderosa, Scots, sugar — distinguished from spruce by needle clusters bound at the base. The color refers to mature pine needles in late summer: a saturated, slightly muted green with the resinous warmth of pine oil. Deeper than spruce, warmer than fir, with the unmistakable association of a forest where the ground is bare but the canopy never empties.

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.
