I know Footy Headlines are usually pretty good with this stuff I can’t figure out how having all three kits as light coloured shirts would actually work. Surely we need a darker one in there somewhere?
I don't think you actually need a dark kit as long as the colors on the 2nd and 3rd kits contrast enough. The mint green will also probably have darker green shorts, I bet.
Pool, Woolwich, Chelsea, Man U, Villa, West Ham, Wolves, Bournemouth, Palace, Forest, Leicester, Everton, City, Ipswich - Away at all these teams, we can wear white shirts and navy shorts, like we historically have. Any of the blue teams (Chelsea, Leicester, Everton, City, Ipswich) we could also wear green and it'd contrast easily.
Brentford, Fulham, Newcastle, Leeds are either all white or wear white stripes with non-blue colors - We should be fine to wear the light blues or greens against these teams. For example, City wear their light blue kits against Brentford and Newcastle.
Brighton's the only team where we have to wear the green kit, and that should contrast fine.
