The old days where house main earthing leads were green 6.0mm2. Ring "mains" were wired in 2.5mm2 T&E with 1.0mm2 earth continuity conductors. And the use of plastic oval conduit in plaster was common.
Is this compliant? Please see picture.

Back to the OP.
Green was considered by many of us to be the proper earth colour. A lot of electricians did not like that new fangled green/yellow combination. Me I didn`t mind and thought it was probably better actually.
Roll foward a bit and the new fangled colours of Brown Blue in single phase was not liked by many even though they were told it was only for flexes say appliances and never for fixed wiring.
Seems a lot of the continent had black for phase 2 and also black again for phase 3. Hmmm - an accident lurking?
Then our three phases all became Brown, Black, Blue - I don`t like them, too wishy washy, Three of the six primary colours for phase such as Red, Yellow, Blue example I thought was pretty good (Red,White, Blue previous - I wonder how they got that ???) .
Years later the Europeans did admit that our RYB was actually better than Br,Bk, Gy but it`s too late now!
Cables in zones is good as a first line of defence but many ordinary people are still now aware of them.
Like on that job I mentioned that wiring routes system did not really surprise me.
They had just bought the house and wanted some extra sockets and some moving an ditto with some lighting. My reply was that it would be more prudent and economical to wire from scratch and just looking at the nail/screw holes in the walls I strongly suspected some had pierced anyway.
