You might want to colour the exclave the same colour as the rest of its country, even though no connection can exist between them on the plane.

It seems like you're using "enclave" and "exclave" interchangeably, which is causing confusion. What you're referring to is an exclave; an enclave is when one region is completely surrounded by another, like Lesotho or Vatican City.

You're right, my first post should say exclaves and the three examples I gave are all exclaves.
