Why not make British English and US English the same? I'm American and we can add a "u" to "color" and replace "ck" with que" in "check". We can even spell "curb" to be "kerb" if you want. Or Britons can change their spellings.
Why not do that, and eliminate unnecessary differences?

I would propose that the Oxford English Dictionary and maybe the US Department of Education (and UK education authorities) could start by agreeing on the "correct" spellings of words and implementing them.
