Composed Kabud

#166dda
Notes

Composed Kabud (#166DDA) is a true azure with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (213°, 82%, 47%) 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 orange. 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.

Kabud
noun

The Arabic word for blue — used in classical Arabic poetry for the blue of the sea, the sky, and Persian-tile mosques. Kabud spans the deep azure-blue range distinct from azraq (sky-blue) and neel (indigo). The color refers to the kabud-glazed dome of the Imam Mosque at Isfahan: a saturated, slightly cool deep blue with the high gloss of fired faience.
