Colours of Mail Boxes

We usually take for granted some daily things like the colour of mail boxes or the year we are living in, and forget that things are not the same in the whole world.

I found in the Wikipedia this map with the colours of the mail boxes in the world. There is also a list that you can consult to discover there are white mail boxes in San Marino, orange mail boxes in Indonesia and grey mail boxes in Philippines (if there is not any mistake in the content).

By the way, I do not know how to add that mail boxes in Morocco are also yellow (like this and this).
