     What is your favorite color? Do you like yellow, orange and red? If you do, you must be an optimistic

 (乐观的), a leader, an active person who enjoys life, people and excitement. Do you prefer grey and

 blue? Then you are probably quiet, shy, and you would rather follow than lead. You tend to be a

 pessimist (悲观主义者). At least, this is what psychologists (心理学家)tell us, and they should know,

 because they have been seriously studying the meaning of color preference (喜好) as well as the effect

  that colors have on human beings. They tell us, among those facts, that we don't choose our favorite

 color  as we grow up - we are born with our preference. If you happen to love brown, you did so, as

soon as you opened your eyes, or at least as soon as you could see clearly.

     Colors do influence our moods. There is no doubt about it. A yellow room makes most people more

 cheerful and more relaxed than a dark green one. And a red dress brings warmth and cheer to the

 saddest winter day. On the other hand, black is depressing. A black bridge over the Thames River near

 London, used to be the scene of more suicides (自杀) than any other bridge in the area - until it was

 repainted green.

     Light and bright colors make people not only happier but more active. It is a fact that factory workers 

 work better, harder, and have fewer accidents when their machines are painted orange rather than black

 or grey.
