As long as earth is identified, the rest have nothing to do with an EICR other than an observation. Table 51 does give the colours for new cables, but each edition of BS 7671 gives the design date at which it comes into effect, so as long as correct at time of design, it still passes for an EICR.
When code 4 was dropped there was a big thing made about the EICR being written in a way Joe public can understand, and it looks for danger and potential danger not compliance with BS 7671.
It does raise issues however, does fitting electronic lighting mean type AC RCD's are not permitted? With TN supplies no, as the RCD is secondary protection, not so sure with TT.
But phase and neutral are both live, so in both cases they should not be exposed, I have spent hours with cable markers numbering cables so to make maintenance easy, it does not say anything in BS 7671, but 31 has always been considered as chassis, and 30 live, so would avoid using 31, in the same way in the British system black was chassis, but in the German system black was live. British Brown was unfused permanent live, Purple fused permanent live, White ignition unfused live, Green ignition fused live until the demise of Lucas, but nothing has been done to get rid of the old British system, it would be near impossible. Be it motor vehicle or 230 volt to earth, we have had it mixed together for years in caravans, and motor homes, and since BS 7671:2008 the regulations have given the pin uses for 7 and 13 pin plugs, the pin 2 of the 7 pin plug has changed though the years, so I always fuse pin 2, it has been air/vac warning, inertia lights, and fog lights.
But I am leaving the subject of cable colours, the use of tracers was common with motor vehicle, but with 230 volt it has always been cable numbers, white, purple, orange, often used for control cables, often 110 volt, but there is very little laid down as to what colour should be used, the only colour which has been set out as special is Green-and-yellow and Cream.
It seems likely the Green sleeve needs changing to Green-and-yellow, but as for rest the sticker "
CAUTION
This installation has wiring colours to two versions of BS 7671.
Great care should be taken before undertaking extension,
alteration or repair that all conductors are correctly identified." should be enough.
