Create a serene and beachy atmosphere in your kitchen with a coastal blue color scheme. Paint the walls a soft blue shade reminiscent of the ocean, and choose white cabinets and countertops to mimic the sandy beaches. Add seashell accents throughout the space, such as seashell-shaped drawer pulls or a seashell chandelier. Complete the look with coastal-themed accessories like a starfish-shaped cutting board or a seashell-printed tablecloth. This kitchen ambiance will transport you to a coastal beach house every time you step inside.
