The "Pan-Arab colors" refer to a set of colors commonly associated with Arab nationalism and unity. These colors are red, black, green, and white, and they are derived from the flags of several Arab countries. Each color has its own historical significance, often linked to the Arab Revolt against Ottoman rule in the early 20th century. These colors symbolize various aspects of Arab identity and heritage. For example, red represents the blood of those who fought for freedom, black symbolizes the dark past of oppression, green signifies the land and prosperity, and white stands for peace and purity. Together, they embody the aspirations of Arab unity and independence.
