Grey is the new red

As I wandered around town the other day, I suddenly noticed that the Father Christmases (or should that be Fathers Christmas?) were dressed in grey.  When did this new fashion start?  Have I been missing something.

Wine seller

Optician

Pharmacy

I also see they are all wearing spectacles.  The first one I noticed was the one in the optician's window and I thought they were being clever.  Then the wine seller had his Father Christmas surrounded by bottles, fair enough, but I started to worry when I got to the pharmacy.  However the worry was unecessary and he was clutching his skis.

I don't know where this fashion for grey came from.  Whatever next?  Grey berries on the holly?
