Hallways are also the perfect place to experiment with and exhibit your creativity. You could opt for a subtle decor if that's your thing or decide to go all out and be absolutely daring with it. Also, the great thing about decorating a hallway is the fact that they are mostly the smallest area in the house and are therefore low-commitment and rather easy to transform it completely quickly. Take risks and in case you do not like it, it would not be a big task to start all over again.
When you are painting the wall with dark colours, you must remember to add a lot of lights to the wall, ceiling or on the table to make them appear brighter. This would also enhance the entire decor and put the focus on the beautiful decorated hallway which was dull and boring a few days ago.
