Why Passports Only Come in Four Colors

Have you ever looked closely at your passport? Did you notice the color? Most passports in the world are red, green, blue, or black. Why are there only four colors?

There is no global rule from the United Nations that decides passport colors. Governments choose their own colors. However, countries choose these four colors for practical, political, and geographical reasons.

Red

Red is the most common passport color. Many countries in the European Union use burgundy or red. Countries that want to join the European Union, like Turkey, also changed their passports to red. Some Andean countries in South America, like Bolivia, Colombia, and Peru, use red too. Red often represents a communist past or present, such as in China.

Blue

Blue is the color of the "New World." Many countries in North America, South America, and Oceania use blue passports. The United States changed its passport to dark blue in 1976. The Caribbean nations also favor blue. Sometimes, blue represents the sea surrounding an island nation.

Green

Green passports are very common in Muslim-majority countries. Countries like Saudi Arabia, Pakistan, and Morocco use green. In Islam, green is a sacred color. It is associated with nature and life. Some members of the Economic Community of West African States (ECOWAS), like Nigeria, also use green to show unity in their region.

Black

Black is the rarest passport color. Only a few countries use it. Botswana, Zambia, and New Zealand issue black passports. In New Zealand, black is the national color. Black passports are also practical because they show dirt less easily. Sometimes, countries issue black passports to diplomats or government officials for high security.

Why dark shades?

Most countries choose dark shades of red, blue, green, and black. Dark colors look more official. They are easier to read and show less wear and tear. A bright yellow or pink passport would get dirty quickly and look less serious at the border.

In the end, a passport is more than a travel document. Its color tells a small story about a country's geography, history, and culture.
