For artists, writers, engineers and other creative professionals, light blue is the best choice.

We all associate colors with feelings and attitudes. In politics, dark blue often means "tradition", and red means "social change". But blue can also mean sadness (I'm feeling blue). White is often for purity, although in China white is worn for funerals, and red is used to express the joy of a wedding, in western Europe white is worn at weddings and black for funerals. Advertisers are aware of the importance of selecting colors according to the way people react to them. Soap powders come in white and light blue packets ( clean and cold, like ice); cereals often come in brown packets (tike wheat fields), but cosmetics never come in brown jars (dirty).

Where do these ideas come from? Max Luscher from the University of Geneva believes that in the beginning life was dictated by two factors beyond our control: night and day. Night brought passivity, and a general slowing down of metabolism; day brought with it the possibility of action, and increased in the metabolic rate, thus providing us with energy and initiative. Dark blue, therefore, is the color of quietness and passivity, bright yellow the color of hope and activity.

In prehistoric times, activity as a rule took one of two forms: either we were hunting and at- tacking, or we were being hunted and defending ourselves against attack. Attack is universally re- presented by the color red; serf-preservation by its complement green.

In Luseher's view, the association of colors with feeling and attitudes can be traced back to______.

A．the association of day and night with passivity and action in ancient time

B．the association of black with funerals in western Europe

C．the association of white with purity in some countries

D．the association of red with joy in China

First read the paragraphs and then find out its problem in writing. Effects of Color Colors create biological reactions in our bodies. These reactions, in turn, can change our behavior. In one study, prisoners were put in a pink room, and they underwent a drastic and measurable decrease in muscle strength and hostility within 2.7 seconds. In another study, athletes needing short bursts of energy were exposed to red light. Their muscle strength increased by 13.5 percent, and the electrical activity in their arm muscle increased by 5.8 percent. Athletes needing more endurance for longer performance responded best when exposed to blue light. Other studies have shown that the color green is calming. Green was a sacred color to Egyptians, representing the hope and joy of spring. It’s also a sacred color to Moslems. Many mosques and temples in the world use green (the color of renewal and growth) and blue (the color of heaven) to balance heavenly peace with spiritual growth. To sum up, color influences us in many ways. (Daniel 10)
