Different countries have different languages and cultures. In this article, I'll simply introduce the meaning of two colors between China and Western countries.
In Chinese culture, red usually represents (代表) something good. The bride and groom (新娘和新郎) usually wear red clothes at their wedding, because they believe it will bring happiness to them. But in Western countries, red is the color of force and it usually represents a strong feeling. Wearing red can make it easier to take action. So when you have difficulty making a decision, just wear red.
Another color is green. In China, green usually represents a new life, which has the same culture with Western countries. However, green is also the color of envy (嫉妒) in Western countries. So people may describe someone is "green with envy".
In a word, it can be said that color words carry different cultures. Learning the difference of color meanings between China and Western countries can not only help us to know about our cultures better, but also open our eyes. And it's also interesting to know about the cultural differences between countries.
