Sanitary Azul

#1f81c0
Notes

Sanitary Azul (#1F81C0) 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 (203°, 72%, 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

Sanitary
adjective

Latin sānitās, health — adjectival suffix -ary. As a color modifier, sanitary implies a clear-and-clean-and-medical quality, the crisp color of Bauhaus-and-Modern clinical-and-hospital interior-architecture white-tile-and-stainless-steel surfaces. Sits at the crisp-and-clean end of the grid, parallel to hygienic and sterile 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.
