Refreshing Ābī

#4c90a7
Notes

Refreshing Ābī (#4C90A7) 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 (195°, 37%, 48%) 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

Refreshing
adjective

Old French refreschir, to make fresh again — present-participle of refresh. As a color modifier, refreshing implies a clear-and-cool-and-revitalizing quality, the crisp color of Cornish-coast and Hebridean-island fresh-sea-air-and-cool-water revitalization. Sits at the crisp-and-cool end of the grid, parallel to fresh and bracing in usage.

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.
