Resilient Kabud

#236dbb
Notes

Resilient Kabud (#236DBB) 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 (211°, 68%, 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 orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Resilient
adjective

Latin resiliēns, springing-back — present-participle of resilīre. As a color modifier, resilient implies a saturated-and-recovering-and-flexible quality where the hue maintains its strength under visual pressure. Sits at the bold-and-resilient end of the grid, parallel to tough and hardy in usage.

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.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
