British English is used in all of the Commonwealth.
Indeed, British English is used pretty much everywhere except America. I don't think I've ever seen a non-American misspell "colour" (though I have seen a few "program"s and "center"s). Where American is used, it's more due to lack of knowledge of British English than actual intent to use the American dialect.
