Sherwin Williams

Sea Serpent

SW 7615

Sea Serpent is a deep blue-gray with noticeable green undertones and an LRV of 7, making it one of the darker options in the Sherwin-Williams range. It absorbs most available light and reads as a near-dark neutral in low-light conditions. The green undertone distinguishes it from pure navy or charcoal, preventing the hue from appearing flat.

It is commonly used on accent walls, cabinetry, and exterior siding. Sea Serpent coordinates with Sherwin-Williams Shoji White for contrast, Greek Villa for trim, Jasper in a tonal scheme, and Halcyon Green as an analogous option.
