[sdiy] Wire Colour coding

[John Blacet]

I actually have been using white for -V for years but don't know if it
is a "standard". Black for common, green not used but could be "digital
common"?

I think you are on your own here; just stick with a system and forget
the system when you go to do house wiring in the US (black is "hot").
