Sinewy Pine

#15a336
Notes

Sinewy Pine (#15A336) 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 (134°, 77%, 36%) 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 magenta. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Sinewy
adjective

Old English sinu, sinew — adjectival suffix -y. As a color modifier, sinewy implies a saturated-and-muscular-and-firm quality where the hue carries the lean-and-strong visual presence of a Roman-statue athletic figure. Sits at the bold-and-firm end of the grid, parallel to stalwart and rugged 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.
