①Colors are often used to describe feelings. For example, if you “feel blue”, it means that you're sad. A person who "sees red" is angry, and someone who's “tickled pink” is happy about something. Besides expressing feelings, though, colors may also influence our actions.

②In Japan, officials have put in blue lights around railroad platforms to discourage people from jumping in front of trains. As a result, certain stations with the blue lights have seen an 84 percent drop in suicide(自杀) numbers. Pink has been believed to prevent crimes. In the United States, rooms in prison(监狱) were painted this color to calm prisoners. In sports, some visiting teams have had to use all-pink locker rooms, which were meant to weaken the team and make them lose.

③Unlike pink, red may let you gain an upper hand in sports. Sportsmen who wore red were found to have a slightly higher chance of winning. Red is also believed to be the color of energy and power.

④The ways in which colors affect us may be a result of nature and evolution(进化). Red is the color of fire and blood. So it is connected to life, danger. Yellow describes sunny days and can make us feel energetic and happy, while blue relaxes us with images of the sea and the sky.

⑤Other factors relating our reactions to colors are culture and history. In the past, the process to produce purple is difficult, and only kings and nobles could afford things in purple. As a result, the color became a royal symbol.

⑥As you can see, colors shape how we understand the world. They are seen in all parts of life and they can influence us in ways that we may not notice.

Colors can affect (影响) our feelings (感受), so knowing something about colors can help us find the right colors in our rooms.

It is easy to see red in Chinese rooms. It is my favorite color. It means (意味着) happiness (幸福). But if your bedroom is red, you may not sleep well. It’s an active color and makes us want to play sports.

Orange is a good choice (选择) for a dining room. People like having dinner and talking together in an orange room.

If you are a student, ask your parents to paint your study (书房) yellow. Yellow can help you think faster. You may be more confident (自信的).

You probably don’t know that many of the walls of the rooms in the hospitals are blue. Why? Because blue can make sick (生病的) people feel quiet. They can have a good rest (休息) and become well soon. So use it in your bedroom and you can have a good sleep.

In English, feeling "blue" means feeling sad. But in 2020, the word "blue" could mean something more positive (积极的) .

The Pantone Color Institute in the US forecasts (预测) color trends (趋势) every year. For 2020, it has chosen "classic blue", a color that reminds people of the sky before dark. The reason is that it brings "calm, confidence and connection," according to Pantone.

In 2020, people all over the world faced big challenges. Climate change, disease, homeless-ness... all of these problems made us feel nervous and uneasy. But as Pantone Vice(副) President Laurie Pressman said, "The color of classic blue has a comforting power."

Imagine that you are lying down on the ground and looking at the evening sky. Looking at the blue sky will make you feel calm and relaxed, as well as make you think on a deeper level.

Pantone said that classic blue connects people everywhere as we all look up at our shared sky. "This is a color we can relate to (引起共鸣) around the world, no matter where we live. We look outside the door and we see this color," Pressman said.

"Like blue jeans, it's always there and you're comfortable with it," said Pressman, who considered classic blue as a " timeless shade". If the color is never out of style, people won't throw "classic blue" things away. We can buy less and save resources.

So if you want to add some new things to your home, choose something blue to keep up with the latest trend.
