The fact that people can "see" things using other parts of their bodies apart from their eyes may help us to understand our feelings about color. If they can sense color differences then perhaps we, too, are affected by color unconsciously.
Manufacturers have discovered by trail and error that sugar sells badly in green wrappings, that blue foods are considered unpleasant, and that cosmetics (化妆品) should never be packaged in brown. These discoveries have grown into a whole discipline of color psychology that now finds application in everything from fashion to interior decoration. Some of our preferences are clearly psychological. Dark blue is the colour of the night sky therefore associated with passivity and calm, while yellow is a day color with associations and incentive (刺激). For primitive man, activity during the day meant hunting and attacking, while he soon saw a red, the color of blood and rage and the heat that came with effort. And green is associated with passive defense and self-preservation. Experiments have shown that colors, partly because of their physiological associations, also have a direct psychological effect. People exposed to bright red show an increase in heart beat, and blood pressure; red is exciting. Similar exposure to pure blue has exactly the opposite effect; it is a calming color. Because of its exciting connotations (涵义) , red was chosen as the signal [or danger, but closer analysis shows that 'a vivid yellow can produce a more basic state of alertness and alarm, so fire engines and ambulances in some advanced communities are now rushing around in bright yellow colors that stop the traffic dead.
