A gray wallpaper mural is key to creating a modern space. Layering lighter and darker shades will create stylish complexity. It’s a classic, neutral tone that allows you to be creative and daring with your interior. A gray wallpaper mural will let you experiment with your furniture, incorporating various colors such as pinks, blues, purples and many more, as it really allows them to stand out. A lighter plain gray wallpaper mural will create calm and peaceful surroundings and therefore would work great in a living room or bedroom. Dark gray and solid gray wallpaper murals promote an industrial, sophisticated and textured feel and therefore could work well in a kitchen or office.
