There are only four primary passport colors in the world. Every country has it’s own reasons for choosing these colors as their passport cover.
We decided to share the information to make you aware about the fact that why countries have chosen these four colors as their passport cover. These four colors are Red, Blue, Green, and Black.
Don’t forget to share this information with your fellows.
Passport with Red Cover
Red is the most common color. Passports with a red cover are often chosen by countries with a historical or current communist system. Citizens of Slovenia, China, Serbia, Russia, Latvia, Romania, Poland, and Georgia have red passports. Member countries of the European Union except Croatia, also use passports of burgundy and other shades of red. Turkey, Macedonia, and Albania, changed the color of their passports to red a few years ago because of their interest in joining the EU. The Andean Community of Nations Bolivia, Colombia, Ecuador, and Peru also has burgundy passports.
Passport with Blue Cover
Blue is another most common color. The blue cover indicates the “new world”. 15 Caribbean countries have blue passports. Blue passport cover of South American countries symbolizes the connection with Mercosur-a trade union. This includes Brazil, Argentina, and Paraguay. Venezuela is an exception here, it also belongs to the union but its citizens have red passports. The passports of US citizens were changed to blue only in 1976.
