Neutrals help to add contrast to a room and they create balance in the color scheme. If your walls are neutral in color you may want to add patterns or more color in your furnishings. If the walls are bright or patterned, you may want to have your furnishings be more sedate. If walls and furniture are neutral, add interest with accent pillows, textures or accessories. Whatever you do, it is important to have contrast in a room.
Ceramic tile is best in a neutral color.
In a bathroom , introduce color into the room with easily changeable rugs, towels and shower curtains. Some dark colors, such as deep green, navy, black, charcoal can be looked upon as a neutral because so many colors go well with them. Vary textures in a room full of neutrals to add interest. If you want a really tranquil bedroom, eliminate vivid colors and use only neutralized colors. Neutrals are best used on finishes that are going to be around a while or would be expensive to replace every few years.
