Sherwin Williams

Aquitaine

SW 9057

Aquitaine from Sherwin-Williams is a cool blue with clear cool undertones at hex #88ABB4, positioned as a mid-tone that neither overwhelms nor recedes. Its LRV of 38 places it in the lower-mid range of light reflectance, giving it enough depth to register as a definitive color statement while still reading as moderate on the wall. The blue leans slightly dusty rather than bright, making it functional across modern and coastal schemes.

Analogous Sherwin-Williams shades like Rainwashed and Quietude extend its cool palette, while warm accents such as Coral Clay or Cavern Clay provide temperature contrast. Neutrals like Alabaster or Snowbound offer a clean backdrop.
