Even the narrowest of hallways can be beautified with intense, bright, dazzling, and unusual colors as well as extravagant pattern wallpapers, and the pattern size and type don't necessarily play a huge role when using it on just a feature wall. For instance, the area with the coat-hanger, perhaps a storage bench, and a mirror can be adorned with just a few strips of wallpaper. On a feature wall, the colors can be fairly dark, too, but they should simply be a pleasing contrast to the rest of the space. In terms of pattern motifs, there is no limit to your choice: baroque ornaments, leaves, petals, flowers, graphic elements, objects, animals. people and abstract images are all possible.
Another increasingly popular variation is putting up a patterned wallpaper on just one wall, whilst using a one-coloured type on the other walls (or just painting them). This method distracts the eye from the narrowness of the hallway and lends it more depth and structure. But some thought is required to make this concept a success. Should it be the left or the right wall of the hall? Don't rely on the principle of chance. The feature wall should not have a door and some daylight would be beneficial. A wall that goes around a corner or has some angles shouldn't present a problem.
Here are some wallpaper patterns and colours that are particularly suitable in terms of providing contrast:
In addition to applying design pattern wallpaper to walls and ceilings, there are a few other factors that will make a narrow hall looks larger and make it feel cosier:
