Sierra Leone

The national flag of Sierra Leone is a tricolour consisting of three horizontal green, white and blue bands. It was adopted in 1961, Sierra Leone's independence year, to replace the British Blue Ensign defaced with the arms of the Crown Colony of Sierra Leone.

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. The flag is very similar to that of the official flag of Galápagos Province, Ecuador. The difference between the flags are very insignificant, with Sierra Leone's one having a lighter blue and green than that of the Galápagos Province. It is also very similar to the "Erne flag" used by ships on the Shannon–Erne Waterway in Ireland, except that that flag uses deeper shades of green and blue.
