When you get tired of homework, several minutes' walk in a nearby green park helps you relax at once. Or you may stand facing the lake or the sea. They'll calm (not to be excited or nervous) you just like the green plants.
    Wonder why? Color is a key part of the answers. Since it is so, green and blue help make people feel more quiet and safe.
    All colors have special power. Scientists have found that many colors have specific effects (效果) on people's minds and feelings.
    Try an easy and interesting experiment and you'll see how color “misleads” you sometimes. Wrap (包装) two boxes of the same size with colored paper, one red and the other white. Then weigh the two boxes with your hands. Which one is heavier? Most people will think that the red box is heavier, even though they weigh the same.
    Colors can affect (影响) learning. Scientists have found that students spend more time reading if they read information written in blue text. Blue helps most people calm down and think more.
    Smart (clever) uses of colors in daily life are to be seen everywhere. Hospital and libraries seldom (很少) paint their walls, tables and desks red. They use light colors, like light blue or green. Red makes people excited while light colors help them relax. Haven’t worked out how color affects your daily life? Start with your small room. Try to make some changes in it and you’ll get to know how important color is!
