If only choosing a color palette for your interiors was that easy. Well .... actually, it is! Our palette-perfecting tips explain the color rules that designers follow and make it a snap to put them to work in your home.

If you've got patterned upholstery, a colorful rug or large piece of artwork, pluck colors you like from the pattern. For a neutral wall paint color, look to the pattern's whites and beiges.

A real "cookbook" way to make any space look good without much risk, says designer Mark McCauley, is to use darker color values for the floor, medium color values for the walls and light values for the ceiling. "Any interior space replicates the outside world," he says. "The exterior environment is generally darker below our feet (the earth itself), medium-valued as you look straight ahead (buildings/trees) and lighter skyward."

Specifically, the living room, dining room and entry way. Choose a color scheme for those areas first, then pull one color from the scheme. For example, take the red sofa and tone it down (say, to burgundy) for an accent in more private spaces such as the den, office or bedroom.
