We have, in order of preference:
Yellow
Black
Red
Blue
We ALWAYS wear black shorts and socks.
Yes, we do carry all four shirts to every game, just in case, but each club is supposed to submit their colours at the start of the season so we should have some idea in advance.
Having said that, my first game last season was Papamoa vs Te Puke: official colours Papamoa - yellow and blue stripes. Te Puke: Red & Black stripes!
Fortunately I had an old design green shirt so threw that in the bag, although when I arrived, Pap had a brand new shiny kit of plain yellow shirts and blue shorts.
