Passports all over the world have color codes. Did you find them in China?

Passports are important documents for us. You must have noticed that passports used in different countries have different colors. For example, American passports are blue and China passports are crimson. But do you know what the rules are? Or what's the difference

This is the "color code" of the passport. Knowing this, you may be able to guess roughly what kind of country a traveler comes from from from the color of his passport.

People who run the global passport data rankings say that there is actually no official regulation on passport color.

However, around the world, passports basically have four main colors: blue, red, green and black, that is, they usually change their hue according to blue, red, green or black, but dark colors-navy blue, deep wine red and forest green-seem to be the most popular colors.

The International Civil Aviation Organization (ICAO) has promulgated regulations on the appearance of passports, including size and format. For example, the size of a passport is 125mm x 88mm.

But governments around the world can choose the color and design of passports, and there are "many possible situations" to explain why they choose a certain color, Bohsian said.

For different countries, they will consider geographical location, politics and even religion when choosing passport colors. Because passports reflect the identity of the country.

Countries with blue passports like the United States include Australia, Canada, China and Hongkong, island countries in Africa, Central America and the Pacific, and CARICOM (Caribbean * * * and * * * with the same market). The use of blue in these countries or regions is considered to have geographical reasons.

According to the preferences of different countries, the same color system will also have great differences in depth.

In these countries, most passports use dark tones, but other countries, such as Fiji, use lighter and brighter sky blue. The color of American passport changed from green to blue on 1976, which is similar to the blue on the American flag.

Similarly, in countries that use red passports, the colors are different, from orange in Singapore to rose in Cyprus, and then to deep wine red, which is deeply loved by Europeans.

There is a saying that deep Burgundy is related to history and social system. Deep Burgundy has now been linked to the European Union, and all member countries adopt deep Burgundy except Croatia, which adopts almost black passports.

Due to Britain's withdrawal from the EU last year, Britain will also change its dark burgundy passport back to its previous blue passport from 20 19. Turkey, which wants to join the European Union, changed its passport from black to deep burgundy.

black

Although it is not so common, it is of national significance to use serious and deep black as passport color in a few countries, including Palestine and New Zealand.

The color of the passport represents the image of the country to a great extent.

"Governments all over the world have the freedom to choose colors and patterns. Unfortunately, only a few people understand the importance of this document to their national standard identity. " Boshian said.

Black is also commonly used in diplomatic passports.

From this point of view, the choice of a country's passport color or influenced by culture and history also depends on practicality and feasibility.

Some countries choose certain colors to distinguish them. For example, Norwegian passports are white, blue-green and red, and the three colors are used by immigrants, diplomats and nationals respectively. Temporary passports issued by Canada to people who need emergency travel documents are white.
