Wallpaper is tricky, it can be a beautiful design tool to enliven a home or, in the wrong hands it can be hellish nightscape of chaos, there is such a thing as too much. Here is a wonderful example of complimentary wallpapers layered between rooms that transitions easily from one space to another. The wide blue stripes in the foyer match very well with the Chinoiserie style flower blossoms.
Why Does It Work?
The combination of the two wallpapers works for a number of reasons, but lets try and break it down a bit. Both color tones are muted and complimentary, a soft pale blue with a light minty green. Both colors also happen to work very well with the medium brown floor stain. The stripes on the wall are medium wide, providing a simply geometry that contrasts the organic flowers and branches of the other walls. All of the door frames, baseboards and molding are reasonably heavy and the thickness of the walls are fairly substantial which helps to break up the patterns and the colors and create frames.
This is not a difficult look to replicate, but its worth knowing why it works visually. Using different wallpapers between rooms should not be terrifying and obviously can be quite beautiful if well executed.
