* ADDRESS THE ARCHITECTURE. Architectural details can be divided into two categories - structural and decorative. Neutral colors work better with structural details such as columns or door frames. Something that looks as if it provides support is not the place for a pale peach color. Decorative colors would be more appropriate with friezes and other ornate moldings.
* REMEMBER: THERE ARE NO "BAD" COLORS. Colors change and create different perceptions, depending on where and how they are used. A very bright, garish green might seem a bad color for a dining room. It could be quite beautiful, however, as a thin stripe underneath crown molding in a beige-walled living room.
* CONSIDER HOW COLORS OF ADJOINING ROOM INTERACT. Colors in abutting rooms tend to reinforce each other - which can have dramatic or unpleasant results. A subtle beige room can appear much stronger if viewed from a subtle blue room (and vice versa). Also, thinking about rooms as a series of colors can make cramped quarters seem roomier. For a three-room apartment, if the kitchen and living room have light, warm colors, a bedroom with stronger and deeper colors can provide a perfect "escape."
