Benjamin Moore

Powell Gray

CW-665

Powell Gray by Benjamin Moore is a muted blue-gray drawn from the Colonial Williamsburg palette, carrying cool undertones that read distinctly blue in certain lighting conditions. Its LRV of 14.61 classifies it as a darker shade, appropriate for creating contained, low-light atmospheres in living rooms, libraries, and bedrooms. The cool blue cast separates it from warmer grays.

Simply White and White Dove provide necessary contrast on trim and ceilings, while Saybrook Sage offers an analogous muted green pairing. Hale Navy and Kendall Charcoal can deepen a tonal scheme built around this shade.
