No Global Rule Sets Passport-Cover Color
There is no worldwide authority that assigns each country a passport color. International standards govern practical features such as a passport’s layout and machine-readable information, but governments choose the cover color themselves. That leaves room for national preference—and for colors that make a passport look familiar within a region or tradition.
Color Signals Identity, Not Permission
Burgundy covers are common among European Union countries, while green appears on passports from a number of Muslim-majority countries. Those patterns can reflect regional conventions or cultural and political associations, but they are not universal rules: countries in the same region may choose different colors, and the same color can mean different things in different places.
A cover color also does not determine whether a passport is valid or where its holder can travel. Those questions depend on the issuing country, the document’s security features, and the rules of the destination—not on whether the cover is red, blue, green, or black. In short, the color is a national design choice, not a global code.
