Need a relaxed atmosphere, so it is best to use a lighter color to spread wall tiles on the balcony.
Generally, it depends on your family style. Now the balcony can not only be tiled, but also covered with sauna boards and the like. There is an idyllic style of returning to nature. If you don't care too much, I suggest you use light color, no matter what color is light color, it will bring you a refreshing feeling.
