I've browsed a few teams on Historical Kits and find it amazing how some teams just changed colours, Not even a gradual change either.
A couple of examples:
Partick Thistle wore Blue and White for some time, then just changed to Red and Yellow hoops.
Dundee Utd, were Black and White for years before just changing to Tangerine.
Leeds Utd, from Yellow and Blue to all White.
Blackpool wore Red tops, then changed to Red, Yellow and Black hoops then to White tops before going back to Red, only to change to Tangerine. Even then they had a mid change to Light and Dark Blue stripes.
Imagine that happening these days. One season we're Claret and Blue the next season Yellow and Green
Although there might be more, only Notts Forest seem to have remained on Red tops White Shorts (albeit a darker shade of Red early on) throughout.
