Cape Cod Blue House with White Trim

Cape Cod blue with crisp white trim is the quintessential American coastal exterior, gracing homes from Nantucket to Newport, from Charleston's Battery to the Outer Banks. The medium-tone blue (similar to Sherwin-Williams Mountain Stream SW 7612 or Benjamin Moore Buxton Blue HC-149) carries enough depth to feel substantial while reading as fresh and breezy in afternoon light. White trim along window casings, fascia boards, and corner boards provides the crisp definition that lifts the blue from the body of the house and gives the facade its signature crisp geometry. This combination has dominated New England real estate listings for over fifty years because it consistently increases buyer interest and selling prices. The palette particularly suits shingle-style cottages, Cape Cod ranches, and Nantucket-style colonials, but also works beautifully on more contemporary homes that want to evoke a coastal vacation feel year-round. The blue is dark enough to hide minor wear and weather staining, which makes it practical for waterfront properties exposed to salt spray and wind-driven rain. In direct sunlight the blue appears almost denim-like, while on cloudy days it shifts toward a soft gray-blue that pairs naturally with cedar shake roofs and slate steps.

For waterfront or salt-air locations, specify Sherwin-Williams Resilience or Benjamin Moore Aura Exterior in this color — both feature mildew-resistant binders and salt-tolerant chemistry. The white trim should be a true bright white, not an off-white or cream, to maintain the high-contrast look. Use Sherwin-Williams Pure White SW 7005 or Benjamin Moore Chantilly Lace OC-65. For the front door, traditional choices include matte black, navy blue (a shade darker than the body), or natural-stained mahogany. Add black or oil-rubbed bronze hardware throughout for the most authentic coastal look.
