Located in north-central Africa, this large country has two official languages – French and Arabic. It is landlocked, with Libya to the north and flanked by Sudan and Niger to the east and west, respectively. 

Chad’s flag is composed of three vertical lines of equal width: blue to the left, yellow in the middle, and red to the right. The exact same color composition is used in Andorra’s flag, the only difference between the two being the seal distinguishing Andorra’s flag from Chad’s unadorned flag.

This large, coastal nation lies at the northern coast of South America, bordering the Caribbean Sea. Full of tropical forests, Colombia has the second-highest level of biodiversity in the world and is one of only seventeen megadiverse countries – a group of nations harboring the majority of Earth’s flora and fauna species. 

Colombia’s flag has three horizontal stripes, with the top yellow stripe encompassing the top half of the flag with blue and red making up the bottom half, the blue and red stripes each making up one-quarter of the flag’s total space.

The Democratic Republic of the Congo – also known as the DRC – is a landlocked country located in central Africa. Formerly known as Zaire, the DRC is home to the second-largest rainforest in the world, thanks to its proximity to the equator and the mighty Congo River. 

The DRC’s flag has a blue background with a diagonal red and yellow stripe running upwards from the bottom left corner of the flag to the upper right corner. A yellow five-pointed star sits in the flag’s top left corner. 

6. Ecuador

Without the national coat of arms, the Latin American country Ecuador’s flag is identical to that of Colombia. Ecuador’s coat of arms sits in the center of the flag – overlapping the border between the yellow and blue stripes. The yellow stripe represents the nation’s gold deposits, with the blue associated with Ecuador’s coast, and the red honoring those who were killed fighting for Ecuador’s independence. 

The ornate seal depicts Mount Chimborazo with a steamboat in the foreground – referencing the first steamboat sailed in Latin America. Ecuador’s national bird, the condor, sits with outstretched wings at the top of the coat of arms. 

7. Kiribati

9. Mongolia

10. Romania

The flag of this eastern European nation has been the subject of controversy since the 1990s due to it being identical to the national flag of Chad. Even in 2004 when Chad’s officials asked the UN to examine the issue, Romanian officials wouldn’t agree to any changes to their national flag.

Romania’s flag represents liberty with blue, justice with yellow, and brotherhood with red.
