The national flag of Guinea was adopted on 10 November 1958.
The colors of the flag were adapted from those of the Rassemblement Démocratique Africain, the dominant movement at the time of independence. The colors were in turn derived from those of the flag of Ghana, which had first adopted them in 1957. Sékou Touré, the first President of Guinea, was a close associate of Kwame Nkrumah, the former president of Ghana.
Red symbolizes the blood of the martyrs who died from slavery and wars, yellow represents the sun and the riches of the country, and green the country’s vegetation. In keeping with other flags in the region, the Pan-African movement’s colors of red, yellow, and green are used.
