Do you guys learn English English or American English or some third thing? Is the big piece of metal that covers your engine of you car a hood or a bonnet? Is the thing out back a boot or a trunk? When it's dark out, do you grab a flashlight or a torch? When getting in the box to take you to a different floor is at an elevator or a lift?
It may be like Quebec. The teacher ends up "deciding" (in fact, the region he comes from decide). A British talks British, an American talks American and a Canadian talks "Canadian" (a wierd mix of American and British). All forms are accepted on exams, obviously, so you can write color or colour, whatever you like.
