The black, white, green, and red on the flag are called the "Pan-Arab colors." These are colors shared by several Arab nations, carrying the meaning of Arab history and unity.

This flag is a powerful symbol of Palestinian national identity and the aspiration for self-determination. That's why it's often used to express political and social support or in discussions about international relations. It's a profound example of how a single emoji can contain a nation's history and hopes for the future.
