Sierra Leone

The flag of Sierra Leone is a tricolour consisting of three horizontal green, white and blue bands. Adopted in 1961 to replace the British Blue Ensign defaced with the arms of the crown colony, it has been the flag of the Republic of Sierra Leone since the country gained independence that year. Both the flag and the coat of arms of the country were formulated and authorized by the College of Arms the year before. ... The colours of the flag carry cultural, political, and regional meanings. The green alludes to the country's natural resources – specifically agriculture and its mountains. – while the white epitomizes "unity and justice". The blue evokes the "natural harbour" of Freetown, the capital city of Sierra Leone, as well as the hope of "contributing to world peace" through its usage. [Flag of Sierra Leone. Wikipedia]
