I know you're insistent on the Navy thing mate, but I don't agree.
Doesn't sit right with me. And as Garry James said, many of those examples of Navy socks come from black and white photos where they may well have been black.
Liverpool used to wear white shorts not even that long ago but from about the 60s on they stuck with a colour scheme of all red.
We need to do something similar IMO, not point to examples where we wore a particular colour scheme and then say it's part of our core colours.
We can agree to disagree like, but I think we should always try and aim for that look we had in the 60s, that's a classic.
That's the image that comes to mind for me, when I think of a 'proper' Manchester City kit.
If I had my way we'd stick to that template every season.
