In case you're curious, there's a reason of sorts behind the green patch here:
Many folks may not realise that, once upon a time, Father Christmas's trademark colour used to be Green. It was only when Coca-Cola and others got involved somewhere in the 30's that a marketing plan of the time saw Saint Nick changed to Red instead. So that's my little nod here.
Least that's what I heard anyway. But this web page from the BBC might help explain things more clearly.
PS: only 24 more shopping days 'till Christmas! =P
