The most important element of design in one’s home is the continuous thread that stretches from room to room. Neutral walls provide a light, airy backdrop against which you can introduce a multitude of color palettes. Neutrals provide a subtle framework for the colors brought into the space through furnishings and art. (The neutral approach is a practical one: Furniture and art are easier to change than wall coverings.) Part of the allure of applying neutral colors is the fact that they allow different levels of light to showcase the room’s various architectural elements: Neutrals reflect the changes in light within a room all day long.
