Sinewy Cedar

#39a647
Notes

Sinewy Cedar (#39A647) 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 (128°, 49%, 44%) 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

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.

Cedar
noun

The genus Cedrus — Lebanon, Atlas, Deodar — the great cedar trees of the eastern Mediterranean and Himalayan foothills, prized in antiquity for the rot-resistant timber that built Solomon's Temple and Pharaonic ships. The color refers to mature cedar foliage: a deep, slightly blue-green with the resinous warmth of cedrol oil. Cooler than pine, drier than spruce, with the architectural weight of a wood that scents whole regions.
