With Navy blue as the most dominant dark color (velvet please) the backdrop for the 4th of July is in place with only vibrant additions needed for the full effect! If your permanent color scheme is not red, white and blue you can add one or more of the colors and a stripe or star between Memorial Day, through Flag Day, the 4th of July to Labor Day for a patriotic touch in the summer months. Seasonal changes add vibrancy to your home and set the stage for a themed party! I love this outdoor sofa from Frontgate.
