Create a modern coastal look in your kitchen with a coastal gray theme. Paint the walls in a light gray shade to achieve a contemporary feel. Choose gray cabinets and countertops for a sleek and sophisticated look. Incorporate seashell accents by using seashell-shaped drawer pulls or a seashell mosaic tile backsplash. Add pops of coastal colors with turquoise or coral accessories. Complete the ambiance with stainless steel appliances and minimalist coastal artwork.
