With dark blue shutters on an egg-blue Ranch-style home, this Florida home fits its location. Consider how combinations of colors bring together your house. Simple changes, like painting the door a dark blue like the shutters, might lend more balance to the curb appeal. With all the work you put into painting your house, curb appeal can be quickly destroyed by a window air conditioner or a more permanent dish antenna. Maybe your first stop shouldn’t be to a paint store. Instead, try the local plant nursery and smell the flowers.
