Pan-Arab colors ( Arabic. ألوان الوحدة العربية - the colors of the unity of the Arabs ) - the colors present on the flags of the countries of the Arab rebellion : red , black , white and green . The first three colors are represented on the flags of Egypt and Yemen; together with green, they are also present on the flags of Iraq , Jordan , Kuwait , Palestinians , Somaliland , Sudan , Syria , the United Arab Emirates and Western Sahara .
It is believed that each color of the four Arabic colors represents a specific Arab dynasty or era: the black color was the flag color of the Prophet Muhammad , while the white color was taken by the Umayyads to be their symbol, since it reminded them of the battle of Badr , the green color was taken by the Fatimids as a symbol of their support for Ali ibn Abu Talib , while the red color was the Kharijit flag and then became the symbol of rulers in North Africa and Al-Andalus.
Some Arab countries do not use all Arabic colors or use some of them in other combinations: Algeria and Lebanon , for example, use only green, white and red without black, Tunisia , Qatar and Bahrain - only white and red.
