Many people take it for granted that black is a color of bad things while white should always mean something good. This may be because, in their opinion, black is related to darkness and white to purity. However, that is not always the case. Did you know that the same one colour may mean differently in different places of the world?
In the English-speaking world, black is the colour of mourning. People wear black clothes at the funeral. Red is concerned with danger or bloodshed (流血). Yellow is the word for fear. If you are afraid, you are yellow. Yet none of these sayings is true outside the English-speaking world. In China and Korea white is the colour of mourning. In Russia, China and some other countries, red stands for beauty, life and excellence. In Italy and Germany, you are yellow with anger, not with fear.
