Hello Andy,
at least since I was a little boy (half a century ago), black used to be 
the colour of the live wire in ordinary cables here in Europe. This is 
because the very first power wires were insulated by strips of linnen 
soaked with guttappercha and natural rubber, filled with soot. Hence: 
black colour for the dangerous one.
House wiring was done with free dangling wires on wall mounted 
porcelaine insulators just below the ceiling (I've seen houses like 
that). The neutral wires weren't insulated at all, later they got a grey 
coating (less soot in them), still later blue as artificial dyes came 
up. This coating made it possible to collect the two wires in one single 
cable. Insanity? Consequence!
