Here’s an open-and-shut case of color therapy sure to make your entrance more exciting. Peruse some hues, then tape a few of your favorite swatches to the door. Study them at various times of day to select the one that best complements or contrasts with your home’s exterior paint. When you're ready to commit, opt for exterior acrylic paint—its flexible, anti-mildew formula is ideal. Remove locks and knobs (or tape them if you promise to paint very carefully), and prep the door by wiping, washing, and sanding it down for optimal adhesion. Prime first, then paint, using a brush for the trim and a roller for wider surfaces.
