Just why would any sensible person want different colours between fixed
wiring and flex?

Fixed wiring is a good example of where sticking to our own standard
would have been more sensible.

Only if you want others to be confused.

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.

It was easy enough to deal with the old colours for fixed and the new
for flexible/portable, whereas the current mix of colours in 3-phase
installations frequently does cause problems and requires labelling all
over the place to try and prevent confusion.

There was *no* good reason to change the colours for fixed installations.
