But did the colorado legislators out law aluminium underpants-- or aluminum underpants?

it one of the few things that really bother me.. i don't care if the Economist (and the UK in general) want to spell center as centre -- but when writing about a happening in DC at the JFK Art Center-- it is just that the JFK Art Center not Centre!

if they want to talk about something happening in Mid town NY, and use the phrase centre city-- OK, then they are not talking about a place with a specific name..

If Alcoa set up a new plant in some old commonwealth county, and calls it, for the sake of local speaker the
"the Island aluminium plant" and not "the Island Aluminum Plant" ok-- but if Alcoa names it "The Kingston Aluminum Plant" you can't just go and change the name!
