The flag of Guinea was adopted on November 10, 1958. The colors of the flag were adapted from those of the Rassemblement Democratique Africaine, the dominant movement at the time of independence. The colors were in turn derived from those of Ghana, which had first adopted them in 1957. Sekour Toure, the first President of Guinea, was a close associate of Kwame Nkrumah, the former dictator of Ghana. Red symbolizes the people's sacrifice, yellow represents the sun and the riches of the earth, and green the country's vegetation.
