Blue paint colors are some of the most popular ones to include in your home because of their versatility and mood-shifting qualities. The best blue paint colors can work wonders: You can use sky blue to set a peaceful scene in your bedroom, a navy blue limewash paint to lend the dining room a layer of drama, and an ocean blue in a bathroom to give your morning routine an optimistic lift. You can’t put blue in a box! This limitless color pairs well with most other colors, materials, and fabrics and works with any interior design style—it’s in a league of its own.
