The meaning of the colours of the Ghanaian flag:

The Ghanaian Flag was designed by Mrs. Theodosia Okoh, a Ghanaian, to replace the flag of the United Kingdom upon attainment of independence in 1957. The Flag of Ghana consists of the colours RED, GOLD and GREEN in horizontal stripes with a five-pointed star in the centre of the gold stripe:

Ghana's principal ethnic groups are the Akans (Twi- and Fante-speaking), the Guans, Ewes, Dagombas, Gas, Gonjas, Dagabas, Walas and Frafras. Twi, Fante, Ga, Hausa, Dagbani, Ewe and Nzema are the major languages, but the official language of the country is English.
