Level Azul

#5599dd
Notes

Level Azul (#5599DD) 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 (210°, 67%, 60%) 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

Level
adjective

Latin libella, small-balance / level-tool — sharing root with libra (balance). As a color modifier, level implies a clear-and-horizontal-true quality where the hue carries the visual register of gravity-perpendicular-and-perfectly-horizontal surface. Sits at the crisp-and-balanced end of the grid, parallel to plumb and flat in usage.

Azul
noun

The Spanish word for blue — used for the saturated deep blue of Andalusian azulejo tile (the same word, al-zulayj, gives Spanish ceramics their name). Azul spans the entire blue-azure range in Iberian color vocabulary. The color refers to a glazed Andalusian azulejo tile: a saturated, slightly cool deep blue with the high gloss of fired ceramic.

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.
