You can start by adding a fresh coat of paint to the outside of the door. Although you want to pick a color that coordinates with the house exterior, you also want to pick something that really stands out. Some popular choices are a kelly green or cobalt blue. And if the exterior already has enough color, maybe go with a bold neutral like charcoal gray.
You can really show your style by swapping out the house numbers too. There are so many colors, sizes and designs to choose from. Check out Etsy for some unique options. Accessories can also add some great detail. Try installing a door knocker, putting down a welcome mat or filling planters with seasonal flowers/plants. If you are feeling ambitious, try changing out the exterior light fixture.
So this weekend, kick the winter blues and dive into spring, door first!
