Is that good?

What, the third phase colour? Definitely! Imagine living in a country
where you can't tell the phase rotation of the mains from the colours of
the wires ;-)

Supplementary question: does anyone know whether the supply industry has
any intention of changing to brown-black-grey phase colours? I bet not.
Reckon they'll stick with their red, yellow and blue discs for a long
time yet...

surely it is easier to differentiate between red/yellow/blue in a dark dirty
hole than brown/black/grey? Plus the colours look a lot nicer )
