Sherwin Williams

Charcoal Blue

SW 2739

Charcoal Blue (hex #3D4450) is a cool-toned, muted navy with distinct gray undertones, registering an LRV of 6, which places it among the deepest colors that absorb most available light. Its blue-gray composition shifts in appearance between lighting conditions, reading richer under artificial light and more subdued in daylight. It works effectively as an accent wall or cabinetry color in both modern and traditional interiors.

Sherwin-Williams Alabaster and Shoji White provide necessary brightness alongside it. Smoky Azurite and Granite Peak offer analogous cool-toned companions, while Tarnished Trumpet introduces a warm metallic contrast.
