Ive seen plenty of red earth in my time, and brown. Don't even have to

But the *covering* is green.

There you go. What's 'logical' to one isn't to another.

Most earth varies around the brown end of the colour scale - certainly not
green.

Copper-coloured wire with a green cover and reddish-brown dirt with a
green cover --- the comparison makes sense to me.

Of course 2/3 of the earth is covered with water, but I don't
recommend this as an electrical technique.


Of course other English speaking countries call the safety
connection 'ground'. Dunno what it's called in other languages.

Green, grass, ground.
