Composed Cuì

#378126
Notes

Composed Cuì (#378126) is a deep 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 (109°, 54%, 33%) 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.

Cuì
noun

The Chinese word for kingfisher — and the saturated blue-green of kingfisher feathers used in classical Chinese cuì-yū (kingfisher feather) imperial ornament. The color refers to a polished fei-cuì (jadeite-cuì) bangle: a saturated, slightly cool deep blue-green with the satin finish of imperial-grade jade.
