Sherwin Williams

Sea Mariner

SW 9640

Yellow Bisque (2023-38) is a light yellow softened by creamy beige undertones, hex #E8D6AB, with an LRV of 65.89 that allows it to brighten a room while keeping the atmosphere low-contrast and restrained. The beige base prevents it from reading as overtly yellow, positioning it as a warm neutral suited to living rooms, kitchens, and nurseries in both traditional and contemporary settings. White Dove and Swiss Coffee maintain a quiet, tonal scheme, while richer pairings with Kendall Charcoal or Hale Navy introduce depth, and softer accents like Woodlawn Blue offer a cool counterbalance.
