Green and yellow wires not used as earth and missing earths.

Please tell me how it is done.

Take a conductor with G/Y (or sky-blue-pink, or whatever) insulation and connect it between a point which is at L potential and somewhere else.

As I've said, this is getting rather silly, and certainly 'unhelpful'

Then stop saying silly things.

Take a conductor with G/Y insulation and connect it between a point which is at L potential and somewhere else.

Exactly. How is that identified as a line conductor?

I'm not sure why you are making an issue out of this, particularly given that we are agreed that the regulation (specifically about just G/Y 'identification') is unnecessary.

You are presumably talking about 'identification' as required by regulations/conventions (which is 'required' so that others can understand the identification). However, that does not alter the fact that you 'can' (even though you 'may not' if you wish to conform with regulations/conventions) identify the usage of conductors (for your own purposes) in any way you choose.

I have various personal conventions as regards 'identification' of conductors (particular in relation to electronics) which would mean nothing to anyone but myself - but that does not alter the fact that I am 'identifying' the conductors in the way that I do.

That's what I thought you meant, which is why I was a bit confused (and now am, again!).

If you so wished, it is surely true that you 'can' ('are able to'), literally/physically, use G/Y (or 'sky blue pink', 'polka dot' or anything else) to identify (for yourself) a live conductor - but you 'may not' do that if you want to conform with regulations/conventions etc.

This really does seem to be an unhelpful diversion, since we both know exactly what the situation is, regardless of 'words'.

And to really add insult to injury in the AV industry cables are often colour coded, often with PVC tape flags. The terminal box pictured earlier often has a set of brown wires with tape flags in the orter: brown, red, orange, yellow, green, blue, purple, grey, white, black [ie the international electrical/electronic colour code] and a matching set of blues in the same way as the numerical cable markers. Worse a bunch of wires in one colour, or a random selection, with 2 flags, as shown plus a brown or a blue.

.... a set of brown wires with tape flags in the orter: brown, red, orange, yellow, green, blue, purple, grey, white, black [ie the international electrical/electronic colour code]

Indeed, that exactyly the sort of 'personal convention' (although, in this case, it would probably be more widely understood) I use with electronics or signalling/control situations, particularly when there are assoiciated multi-pin connectors etc.

... so, in that context, to me brown identifies a conductor as being "#1" and blue identifies it as "#6" (not 'line' and 'neutral').

Absolutely, And I've known inspections to fail when brown flagged blue or green and blue flagged brown or green etc. by house bashers trying to make their theories stick in a field they don't understand.
A completely different situation but demonstrating the principle:

I wonder what (if they also misunderstood the scope of an EICR) they would have to say about the 'identification' of my incoming neutral (red insulation with a brown sheath!) (this pic taken before the most recent meter-changer 'covered yp the evidence' with grey silicone ) ...
