The colors that Africans avoid mainly include the following:
1. Black: In some African countries, black is considered the color of mourning and sadness, so people usually avoid wearing black clothes when attending funerals or other sad occasions. Black is also considered an unlucky color and may be associated with negative symbols in various cultures and religious beliefs.
2. Blue: In countries such as Egypt, blue is also one of the taboo colors. This may be related to the local religious beliefs, cultural traditions, or historical background.
3. Purple and yellow: These colors are also considered unlucky in certain regions of Africa. Especially yellow, in some African countries, it may symbolize death or despair, so special caution is needed when using it.
There may be differences in color taboos among different African countries and regions, which are often closely related to local religious beliefs, cultural traditions, historical backgrounds, and social customs. When interacting or conducting business activities with Africans, it is advisable to avoid using colors that are taboo to them, in order to avoid unnecessary misunderstandings or conflicts.
