There is a large diversity of wallpaper types to choose from. Some feature very simple designs and patterns while others are a burst of energy. Depending on what you are trying to achieve by using wallpaper in the bedroom, you can either choose something simple and delicate for an overall serene and calm décor or something dynamic and colorful that would bring everything together and would cheer up the atmosphere.
Usually the star of the wallpaper design is either the pattern or the color. An intricate pattern would stand out more if combined with simple, neutral colors while a simple pattern could use some bold shades.
