bLack was bLue, as neutral with t/e but can be bRown sleeved like grey
bRown is Red
grey is extra to use as a strapper or switch line if u bRown sleeve it

Sort of sounds a bit Swahili when I read it back, but does make sense..sorta

You are basically right with what you say.

Old colours > New Colours

Red = Brown
Yellow = Black
Blue = Grey


Yes we do sleeve the Black and Grey with brown sleeving.
Also on one way switching you may have a blue wire (when using the new colours) which will also need sleeving brown.

Why do you sleeve the black and grey when they are already phase colours? I cant recall seeing the yellow & blue sleeved red in 2way switching circuits?

They should have been though IIRC. On a single phase install, any phase conductor must be identified red - i thought this was the rule anyway.

EDIT: On a new colour install, they must be coloured brown.
