Colours often have different meanings in different cultures. In the U.S., people have found the following to be true.
Black
Black is the colour of power. It is also popular in fashion because it makes people appear thinner.
White
White is the symbol of purity. White is thought to be a summer colour. However, white shows dirt and is more difficult to keep clean than other colours.
Red
This is the most exciting colour. Red furniture (家具) should look very good since it will attract a lot of attention. Red cars are the thieves’ favourite. Red is often used in restaurants because it is an appetite (食欲) stimulant. This means it can make people eat more.
Blue
Blue is the colour of the sky and the ocean. Peaceful blue is often used in bedrooms. Studies show that weightlifters are able to lift heavier weights in blue gyms.
Green
Green represents nature. It is the easiest colour on the eye. Hospitals often use green because it relaxes patients.
Yellow
Sunny yellow is a cheerful colour, yet people lose their tempers (发脾气) more often in yellow rooms, and babies cry more.
