Loud Ābī

#1bddfd
Notes

Loud Ābī (#1BDDFD) is a true cyan with a neon character. It sits at the high-saturation edge of its family. Use it sparingly, as signage, accent, or highlight against darker surfaces. Its HSL profile (188°, 98%, 55%) 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Loud
adjective

Old English hlūd, making noise — borrowed metaphorically as a color word since the nineteenth century. Loud red, loud yellow: a color so saturated it announces itself without needing surrounding context. Sits in the bright-bucket extreme alongside electric and striking. Carries a slightly pejorative implication of excess.

Ābī
noun

The Persian word for water-colored (from āb, water) — used for the saturated turquoise-blue of Iranian tile and the ābī glaze of Safavid pottery. The color refers to a polished ābī tile from Isfahan's Imam Mosque: a saturated, slightly cool deep blue-green with the high gloss of fired faience.
