     As is known to all, colors appear in every language to express people's feeling and thoughts. Then, what is

the situation in American English?

     Red is a hot color. Americans may say they are red hot about something unfair. They are red hot when they

are very angry about something. The small hot-tasting peppers found in many Mexican foods are called red hot

for their color and their fiery taste. Fast loud music is popular with many people. They may say the music is

red hot, especially the kind called Dixieland Jazz.

     Pink is a lighter kind of red. People sometimes say they are in the pink when they are in good health. The

expression was first used in America at the beginning of the twentieth century. It comes from the fact that

many babies are born with nice pink skin that shows that they are in good health.

     The color black is often used in expressions. People describe a day on which everything goes wrong as a

black day. People or things on a blacklist are connected with things illegal now. But at one time, some

businesses refused to employ people who were on a blacklist for belonging to unpopular organizations.

     The color green is natural for trees and grass. But it is an unnatural color for humans. A person who has

a sick feeling in his stomach may say he feels a little green. A passenger on a boat who is feeling very sick

from high waves may look very green.

     Sometimes a person may be upset because he does not have something as nice as a friend has. That

person may say he is green with envy. Some people are green with envy because a friend has more dollars
