We’ve all stood in long queues, dealt with unscrupulous ‘touts’ just to get that coveted blue booklet; but do we actually know why Indian passports are blue in colour? Or for that matter, how is the colour of a country’s passport decided?
Countries have the liberty to choose the colours of their passports, something which, the “broad spectrum” of passport designs lays testimony to.
However, there is a general trend that is observed when it comes to countries and passport colours.
Several countries have adopted common designs through mutual consent.
The members of the CA-4 Treaty (El Salvador, Honduras, Guatemala and Nicaragua) have a common design passport, known as the Central American passport, which is navy blue in colour.
