Create a serene and inviting kitchen with a coastal blue theme. Paint the walls in a soft blue shade reminiscent of the ocean. Choose white cabinets and countertops to create a clean and fresh look. Add beachy accents such as seashell-shaped drawer pulls, a glass mosaic backsplash with shades of blue, and a nautical-inspired pendant light. Complete the look with coastal decor like a woven jute rug, a driftwood centerpiece, and a collection of seashells displayed on open shelves.
