Colors are sometimes called hot，cold，or neutral(中性). Red and yellow are said to be hot

colors because they make a room feel warmer and the walls nearer to us than they really are. We say that blue and green are cold because they give us the opposite feeling. A neutral color is one that does not seem to affect our feelings. Brown and grey are both neutral，and they may also be mixed with hot or cold colors to reduce their effect on our feelings.

We can begin to see the importance of color selection. Although red might be perfect for a restaurant，it would be wrong for an art exhibition room，where we want to look at the paintings，not at the walls behind. Because of its effect on size，white could be used to make a small room seem larger，or dark blue to make a large one seem smaller.

Another way that we sometimes speak of colors is to say that they are loud or quiet. Again we are talking about the feeling that colors give us. We use sound to express how much colors catch our attention.
