Neutral paint colors are not simply beige, beige or beige. Any shade of gray, white or black is neutral, in that these colors tend to go with any other color. A neutral color is simply one that won't "fight" with stronger colors. Even in the "beige" color palette there are warmer and cooler beiges; beige with gold, green or brown undertones; and very deep or very pale beige. Neutral colors don't have to be boring, and can bridge the space between two rooms painted in vibrant colors. A hallway or foyer painted in a warm golden beige can be a perfect transition color between your red kitchen and rich gold dining room.
Create harmony and flow by using different shades of the same color. Choose a warm tan for larger spaces, a rich brown from the same color family for more intimate rooms such as a small study or formal dining room, and a light, fresh tan for ceilings or woodwork, or for walls in a room with dark-colored furniture for contrast.
If you have several different paint colors throughout your house, unify them by using the same color trim and ceilings throughout. This helps keep the transition from room to room less disjointed. If your wall colors are light and airy, consider crisp pure white for the trim and ceilings. For a more dramatic, jewel-toned color palette, paint the trim and ceilings creamy white or very pale tan.
Large or long walls that link together two distinct spaces, such as a kitchen and family room, can be especially challenging in a multicolor paint scheme. Simply painting a straight line between colors often looks awkward. Depending on your home's style, a faux column or beam built onto the wall and painted or finished the same color as the rest of your trim can look very natural. The Benjamin Moore paint company suggests being creative with a geometric pattern, curved lines or stripes where the two colors meet.
