One way to style a kitchen with a coastal nautical theme is by choosing a color scheme inspired by the beach. Opt for a combination of nautical blue and crisp white to create a fresh and airy atmosphere. Paint the walls in a soft blue shade and incorporate white cabinetry and countertops. Add pops of color with blue and white striped curtains or a nautical-themed backsplash. Complete the look with beachy decor such as seashell-shaped drawer pulls or a ship wheel wall clock.
