Although it might not seem so, but it takes thought and restraint to keep a room white.
A relative of mine has a living room which is primarily cream and ivory and I initally felt very tempted to recommend splashes of duck-egg blues and pale greens just to add some interest. But after spending some time there the need disappeared. Using pale colors can be so soothing and if done well it can work.
Waking up in this bedroom must be glorious.
