Twin Flags — Who Is Who?

Explanation: Almost identical to Chad! Romanian blue is cobalt (lighter) while Chadian blue is indigo (darker). Adopted in 1848.

Explanation: Chad protested at the United Nations against the resemblance with Romania, without success. Both countries refuse to change.

Explanation: Identical to Monaco but in 2:3 proportions (vs 4:5). The red and white come from the 14th-century Majapahit Empire.

Explanation: Identical to Indonesia! Monaco claimed precedence (1881 vs 1945) but both kept their flags.

Explanation: Ireland is green-white-orange from left to right. Ivory Coast is orange-white-green (reversed!).

Explanation: Exact mirror of the Irish flag. Orange symbolizes the northern savanna, green the southern forests, white peace.

Explanation: The oldest tricolor in the world (1572). Luxembourg uses a lighter blue (sky blue vs cobalt blue).

Explanation: The only difference is the shade of blue: sky blue for Luxembourg, cobalt blue for the Netherlands.

Explanation: Iceland uses the same colors but reversed (blue background, red cross bordered in white).

Explanation: Mirror of Norway. Blue background with red cross bordered in white, adopted in 1915 to distinguish itself from Denmark.

Explanation: Guinea is identical but with reversed colors (red-yellow-green). Senegal has an additional green star.

Explanation: Colombia, Ecuador and Venezuela share the same Miranda tricolor. Colombia is distinguished by the absence of a coat of arms and the wider yellow stripe.

Explanation: Bahrain has 5 white points (5 pillars of Islam), Qatar has 9 (maroon instead of red). Bahrain was solid red before 1820.

Explanation: Tunisia has a very similar design but with a white circle in the center containing the crescent and star.

Explanation: Cameroon has a yellow star (not green) and vertical stripes. Mali is identical to Senegal but WITHOUT the star.

Explanation: El Salvador, Honduras and Nicaragua share this blue-white-blue tricolor inherited from the Central American Federation (1823-1841).

Explanation: Often confused with Italy (vertical) or Bulgaria (white-green-red). Iran also has a horizontal green-white-red tricolor.

Explanation: White on top, red on bottom (the exact inverse of Indonesia and Monaco). National colors since the 13th century.

Explanation: Without the coat of arms, Peru is vertical red-white-red, like Canada! But the Peruvian coat of arms makes the difference.

Explanation: The Cedar of Lebanon in the center distinguishes this flag from Austria. The cedar is a biblical symbol of strength and eternity.
