In the "old days" tails used to be redinsulated and sheathed, and black insulated and sheathed. For some reason they changed to red and black insulated and grey sheathed, and subsequently brown and blue insulated and grey sheathed.
I have always thought it best to identify the grey sheath and used to think vinyl tape was suitable, but it degrades, possibly from the plasticisers.
You can get multicoloured packs of cable ties now which seem better, though they may fade in time. The meter fitters use a similar tie.
