Remove all carpeting in the hallway and install wide-planked knotty pine floors, an authentic detail from original colonial homes. Add a simple rug, such as a braided rug in muted colors, to the floors, or keep them bare.
Paint the walls a color typical of colonial homes, such as cream, yellow, blue or green. While wallpaper was rare in authentic colonial homes, you can use it if you are looking for a more ornate or modern effect. Stick to understated patterns and typical colonial colors.
Add brass or wrought iron wall sconces to the hallways, keeping them illuminated and cheerful.
Add a simple, understated wood accent table to one corner of the hallway. Place a simple blue and white porcelain vase on the table with a short-stemmed bouquet of flowers.
Add a simple dried flower wreath to one of the walls or a small wooden hanging clock.
