Sierra Leone — World Flags

The story behind the answer

Sierra Leone’s flag has three horizontal stripes—green, white, and blue—so Sierra Leone is the correct answer. It’s distinct from Mali’s vertical green‑yellow‑red, Kenya’s black‑red‑green with a Maasai shield, and DR Congo’s sky‑blue with a red diagonal stripe and yellow star.

The colors reflect the country: green for its forested hills and agriculture, white for unity and justice, and blue for the Atlantic Ocean and Freetown’s famous natural harbor, founded in the 1790s as a home for freed enslaved people. Memory tip: think “Sea”-rra Leone—blue sea at the bottom, green mountains above, with white peace and justice in between.
