Take the standardisation of mains flex colours - to get back to DIY.
Plenty objected to it on principle, and some still do years after the

the same logic did not apply to fixed wiring.

Please explain the logic of having different colours for fixed wiring and

The two do not normally meet unless you are an electrician. In an existing
installation which has "new wiring", black might be neutral or it might be
a phase colour.
