Sherwin Williams Sea Serpent SW 7615

Sherwin Williams Sea Serpent SW 7615 is a deep blue with a noticeable blue-green cast, like the darker water near a rocky shoreline. It reads cool and inky on the wall, though warm lamps can pull forward a softer teal undertone in the evening. In a north-facing room, expect it to look especially dark and moody, so it benefits from crisp warm-white trim, pale linen curtains, and plenty of layered lighting. Sea Serpent is particularly effective on kitchen or built-in cabinetry, a dining room wall, or a front door where its depth feels intentional rather than heavy. Pair it with natural oak, walnut, aged brass, creamy stone, or muted terracotta for contrast that keeps the blue from feeling overly nautical.
