Not all that different. Our team colours and which one is emphasised (claret over blue or blue over claret) are as much of a design choice as our badge is and could also be up for negotiation at the whims of any current or future custodians.
They'd be total idiots to do so, but, as you say, it's a "business at the end of the day" and there's not much we could do about it if they decided in was in our best interest (e.g. if they wanted to make us more distinctive from other claret-and-blue teams like West Ham).
Villa Park is part of our heritage too. However, like the badge and our team colours, it doesn't 'matter' over and above the results or how we perform on the pitch, and the location of the stadium is almost certainly going to be up for discussion at some point. So, likewise, wouldn't it bother you if we were winning trophies but were playing in a brand new stadium in another part of the city?
