The flags of Ghana and Biafra are based on Pan-African colour schemes. The Ghanaian flag is inspired by the traditional Pan-African colours borrowed from the Ethiopian flag (red, gold and green).
Ethiopia represents the only sovereign African nation during the colonial era, and the tricolour has come to symbolise the African struggle for freedom.
After Ghana adopted the colour scheme, several African nations followed.
The Biafran flag is inspired by the Pan-African flag designed by Marcus Garvey’s Universal Negro Improvement and the colours red, black and green symbolise the fight for black liberation.
