What is your favourite colour Do you like yellow, orange, red If you do, you must be an optimist, a leader, an active person who enjoys life, people and excitement. Do you prefer greys and blues Then you are probably quiet, shy, and you would rather follow than lead. You tend to be a pessimist. At least, this is what psychologists tell us, and they should know, because they have been seriously studying the meaning of colour preference, as well as the effect that colours have on human beings. They tell us, among other facts, that we do not choose our favourite colour 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.
