Create a serene and beachy atmosphere in your kitchen with a coastal blue color scheme. Paint the walls a soft shade of blue and choose cabinets in a crisp white color. Add seashell decor accents such as a seashell-shaped soap dispenser, seashell-printed curtains, and seashell-shaped cabinet knobs. Complete the look with coastal-inspired accessories like a driftwood centerpiece, a woven seagrass rug, and a collection of glass jars filled with sand and seashells.
