#6 Layer It Up
If you think that too much of a good thing is, well, too much, then I invite you to reconsider. Layering the same colour can often have a calming effect, as it can diminish sharp contrasts within a space. Here the walls and drapes make a happy duo, enveloping the room in a soft shade of blue to create a soothing and sophisticated space.
