Wow, I Never Knew

Many of us have travelled extensively, and something I always look for when I’m in lineups at airports, is other people’s passports. I am always curious where people are from, and am intrigued by the different colours of passports.
Did you know, the colour is actually significant? The four common colours you see in passports are blue, maroon, green and black. There are no international regulations for passport colours; however, countries continuously choose one of these four colors to reflect their belonging to international associations, their culture, and heritage. For example, the majority of countries, which belong to the European Union, issue maroon-coloured passports to reflect their membership.
There are also countries like Turkey, for instance, who have switched to maroon passport covers, as they want to belong to the EU. There are, of course, exceptions to the rule. Croatia, for example, has a dark blue passport, because their passports have been blue since 1991, when the country declared independence from Yugoslavia. In Sweden, people who have lost their travel documents get a bright pink, temporary passport. Nothing like telling the world you lost it.
Islamic countries favour green as a colour for their passports, and some African countries, where Islam plays a major role in their culture, also choose green. This is why green is often featured in the flags of these countries.
Black passports are very rare. New Zealand issues passports in this colour, because, as most rugby fans know, black is the country’s national colour. There are some African countries, such as the Congo, Botswana, and Angola who also issue black passports, as does China.
Those of us from Canada and the US, know that our travel documents are blue. Did you know there are 81 countries (out of a total of 203), who also have blue passports? These are mainly countries from the Caribbean. Australia, Ukraine, Hong Kong, and India. Prior to 1976, American passports were issued in various shades of red, green, and even beige, at different time periods.
It made me wonder why most passports are dark-coloured. The
