Why is pink or purple a color for girls and blue or brown for boys?
The answer depends largely on cultural values as well as personal experiences. To the Egyptians， green is a color that means the hope and joy of spring， while for Muslims， it means heaven. Red stands for good luck in many cultures. In China， children are given money in a red envelope to bring good luck in the New Year. For many nations， blue stands for protection. Greek people often wear a blue necklace hoping to protect themselves from bad people or bad things happening.
People’s choice of colors is also influenced by their bodies’ reactions (反应) toward them. Green is said to be the most restful color. It has the ability to cut down pain and relax people both mentally and physically. People who work in green environment have been found to have fewer stomachaches.
Red can cause a person’s blood pressure (血压) to rise and increase people’s appetites (食欲). Many designers will include different shades of red in restaurants. Similarly， some websites will have a red “Buy Now” button because red is a color that easily catches a person’s eyes.
Blue is another color which can make you feel peacefully. Unlike red， blue can cause people to lose appetite. So if you want to eat less， some suggest that eating from blue plates can help.
The next time you are deciding on what to wear or what color to decorate your room， think about the color carefully.
