In the seventies and eighties, American homes usually contained single color schemes � like a bedroom would be done in various shades of blue � but the trend has drastically changed in recent times. Now people are more in contrasts. Do not be surprised if your interior designer suggests a starkly black and white color combination for your kitchen. Or some other such combination that have colors that are poles apart.
