     What is your favourite colour? Do you like yellow, orange or red? If you do, you must be optimist (乐观

者), a leader or an active person who enjoys life. Do you prefer grey and blue?

     Then you are probably quiet, shy and you'd rather follow than lead. You seem to be a pessimist (悲观者).

     Colours influence our moods, there is no doubt about it. A yellow room makes most people feel more

cheerful and warmer than a dark green one. It seems that a red dress brings warmth and cheer. On the other

hand, black is depressing (令人压抑的). A black bridge over the River Thames, near London, used to be the

scene of more suicides (自杀) than other bridges in the area until it was painted green. The number of suicide

attempts (企图) fell sharply at once, perhaps it would have fallen even more if the bridge had been done in pink

or baby blue. Light and bright colours make people not only happier but also more active. It is true fact that

factory workers work better, harder and have fewer accidents when their machines are painted orange rather

than black or dark green.
