Why Is Your Passport One of Four Colors
My passport is dark blue. The passports of my family members from other countries are also dark green, burgundy or navy blue. Thinking about it now, I don’t think I’ve ever seen, say, a hot pink passport. It turns out there is a good reason for this, but that is not what you think.
According to Travel + Leisure, there is actually no official rule that a country’s passport must be a specific color , even if all passports appear to be black or shades of blue, green, or red. If suddenly the color of the US passport changes from dark blue to maroon, it will be okay if the paper material can bend, withstand temperatures between 14 and 122 degrees Fahrenheit, and be readable up to 95% humidity.
But while there are no hard and fast rules governing color, there are practical reasons for darker shades: they make the passport more “official” and better mask traces of dirt and other defects from regular wear and tear. In addition, Travel + Leisure notes:
… geopolitics and religion certainly come into play when a country decides the color of its passport. Muslim countries, for example, tend to prefer green passports because hue is very important to religion. And the Caribbean states usually opt for blue passport covers.
