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 tell us，and they should know, because they have been seriously studying the meaning of color preference，as well as the effect that colors have on human beings． ．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．
