Harmonised 3core + earth

[ajg]

Which colour is used for swithched live and which colour for neutral when using the harmonised 3 core + earth cable to wire an extractor fan with timer?
I knew where I was with the old scheme, do I now use black for the switched live and tag it brown? Do I use grey for neutral and tag it blue?
BS7671 Amendment No 2 doesn't seem to help.

You got the idea!

Doesn't make any odds, would work either way, however, I think most people are adopting the route of neutral being grey, and sw live as black.

Need to sleeve the black and grey appropriately.
