Curious.

As long as I have been aware of it (probably 35 years since I first
wired a plug) it was red for live and black for neutral in fixed
wiring, and brown for live and blue for neutral in flex. (I presume
that before I noticed they were both red/black). We recently switched
fixed-wiring to brown/blue (which I thought was euro-harmonisation
too).
At the same time 3-phase went from red/blue/yellow with a black
neutral to brown/black/grey with a blue neutral.
So now blue and black can both be live or neutral.
