Composed Matcha

#508a16
Notes

Composed Matcha (#508A16) is a deep lime 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 (90°, 72%, 31%) 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 indigo. 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.

Matcha
noun

The shade-grown, stone-ground green tea of the Japanese tea ceremony — leaves of Camellia sinensis covered for weeks before harvest to concentrate chlorophyll, then powdered in a granite mill. The color refers to ceremonial-grade matcha whisked in hot water: a saturated, slightly muted green with the powdery finish of micron-scale leaf particles. Brighter than sage, deeper than lime, with the meditative weight of a 600-year-old practice.
