Representation of Passport Colors:
- Blue: The American flag has a significant amount of the color blue in it, and so does the American passport. But only after 1976, before that they were black. It is further regarded as the color of the “new world,” our oceans, water and the sky – the best color for relaxation and meditation.
- Green: The color green has special religious meaning to most Islamic states around the world; therefore most of the Islamic region passports consist of green color. But they are not the only ones; South Africa, Nigeria, and Senegal have green passports as well.
- Red: Many of the Nordic countries have red passports, given the fact that red was a popular color during the Viking Age and can be found on many of the national flags. Passport for countries within the European Union also consists of a shade of burgundy.
- Black: Black passports are the rarest of the bunch. African nations typically have black passports where black plays a prominent role. The black passport is the one used for people who are traveling on diplomatic missions. Just like the maroon ones, these passports are valid for five years.
