Always bemuses me when people say navy blue is not a City colour. It's been part of our kit since the 1800s. We've had navy blue socks for 70 years of our history, far more than any other colour.
I get that mate, just think it doesn't belong in the crest, and would look fucking dreadful.
Would be too many colours going on for me, and would look too Coventry City for me.
I don't like the way Nike seem to be continually throwing Navy into our kits either, navy trim everywhere, sky blue shorts etc.
I know a lot of blues like the Navy socks, Ian above too, but they're not for me personally.
What I'd really like to see us do is adopt a specific kit template and just fucking stick with it. Really gets under my skin to see it change so often, just seems to disrespect our heritage and give the impression we have no tradition.
You wouldn't see Real in black shorts, Liverpool in white shorts, Arsenal in red shorts, Chelsea in white shorts, the scum in white socks etc etc.
Really quite irritating.
Wouldn't be against having Navy blue socks in the odd away to avoid colour clashes like we've done in recent years when we've worn the home kit, but besides that I think we should be Sky blue and white.
