Front door, archway --- Blue Door Against a Mix of Colors Not a fan of vibrant blue front doors? Consider a darker blue that reads almost gray. This color works with any architectural style, as well as on a house clad in a variety of materials in a variety of colors. It's a superb choice here, as it picks up some of the blue-gray tones in the stone. The gray-blue door acts as a neutral and grounds the entryway.
