Composed Cedar

#377b17
Notes

Composed Cedar (#377B17) 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 (101°, 68%, 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

Composed
adjective

The past participle of compose, to arrange together — used as a color modifier for hues that read as deliberate and balanced. Composed black, composed gray: the saturation is moderate, the hue is calmly positioned without aggression. Sits at the bold-and-quiet edge of the grid near settled and resolute.

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.
