Look back through history at our primrose and blue kits and we always had white shorts and a white collar:

(I'd personally love that kit ^ with slim hoops - not as thin as that kit we had against St George the other year - white shorts and a white trim around the neck...perfect Wire kit!)
Here's another pic in colour

Our p+b kits were like this up until about the 1970s
Also why do we never see another of our historical kits; white with p+b band in the middle:
Leeds were given one in the 2015 CC Final we should have had as a kit:

And Boca Juniors for their away kit this year;

When was the last time we had one of those kits?
How come we've seen so much blue as a predominant colour in recent history?
I really like the recent nod to Zingari for our away kits though. They're really classy and good colours.
