Sherwin Williams

Tidewater

SW 6477

Tidewater is a light, cool blue from Sherwin-Williams with a clear green undertone that shifts it toward an aqua-tinged neutral. With an LRV of 65, it reflects a good amount of light and reads as a bright, open tone on the wall without appearing washed out. The low chroma keeps it muted enough to function as a background color rather than a bold statement.

It is frequently used in bathrooms, bedrooms, and coastal-themed spaces. Tidewater sits comfortably next to Sherwin-Williams Sea Salt and Rainwashed in an analogous palette, while Accessible Beige and Shoji White add warm neutral grounding. High Reflective White provides clean trim contrast.
