The national flag of Guinea (French: drapeau national de la Guinée) is a triband of red, yellow, and green. It was adopted on 10 November 1958, with the publication of the country's first Constitution. It uses the Pan-African colours, partly as a nod to the flag of Ghana, whose president was a close associate of Sekou Toure, the first Guinean president. It is a tricolour resembling the flag of France, its former coloniser.
