Antique Ābī

#688b90
Notes

Antique Ābī (#688B90) is a true cyan with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (188°, 16%, 49%) places it in the muted 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Antique
adjective

Latin antiquus, ancient — used as a color modifier since the seventeenth century for hues that read as if from a previous era. Antique brass, antique rose: moderate-to-low saturation combined with the optical impression of historical patina. Sits at the hushed-bucket alongside aged and heritage.

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.
