The first thing to consider when choosing an exterior paint color for your home is whether there are any restrictions in place in your neighborhood. Next, think about any elements of your home that you have already chosen or that are already in place, and also look at nearby houses.
Some neighborhoods have homeowners' associations with rules about the exterior colors of the homes. Be sure your choice meets the approval of the HOA.
If you are repainting your home, you want your colors to coordinate with existing features, such as the roof or landscaping. Think about highlighting an undertone already in place. If you are building, consider an overall color palette for the various elements.
Though your house does not necessarily have to match the house next door, do not choose a color that clashes with it either. Doing so damages the curb appeal of both homes.
