Embrace a nautical theme in your kitchen by incorporating navy blue accents. Paint the lower cabinets in a deep navy shade and keep the upper cabinets white for a contrasting look. Install brass or chrome hardware to add a touch of elegance. Choose a white subway tile backsplash to create a classic coastal feel. Enhance the nautical vibe with striped curtains, anchor-shaped wall hooks, and rope-inspired drawer pulls. Display vintage nautical maps or hang a ship wheel on the wall as a focal point.
