So you don't think it is confusing for 3-phase installations with a mix
of existing and new circuits to have blue as both a live and a neutral
and black as both a neutral and a live? Often in the same circuit as
parts are replaced or extended.

When you start out with countries using very different standards for wire
colours, there is bound to be this sort of thing. If not in the UK, then
elsewhere. So it is bound to be a compromise somewhere in that
standardised area.

I'm surprised it gives you so much trouble. After all on a standard
domestic lighting circuit it was the norm to use the colour marked as a
neutral as the switch return. Hopefully sleeved to denote this - but most
usually not. Same with triple and earth. Used to a thermostat which needed
a neutral.
