One other thought - presumably the driving force behind this is how many shirts the club will sell. In which case, why don't the club consult the fans? I don't think many would have voted for a yellow shirt with green sleeves.
I just don't get the dreadful green. Who chose that colour for the sleeves? Black would have been much better - or blue. Has no connection with the club and makes us look like Norwich. And we'll be wearing it at all the big away matches. It's a FAIL from me.
