As a corollary to my earlier thread, I have also seen white sleeving on the earth. I thought green was used before the present green and yellow. Was white ever used to represent earth?
Sleeving the earth - my imagination?

I think it was in at least one country, before harmonisation of colours, Germany used Red for earth
Was that country Scotland :-)
Green then later green/yellow has always been the colour for a protective conductor (earth or bonding).
However you may find Cream colour insulation on functional earth[1] conductors (which are normally only found in comms and audio distribution circuits rather than power)
[1] Usually a "clean" earth for noise suppression purposes.
And most RCBOs:-)
Not as sleeving. See John's reply about functional earth colours.

Or for earth recall on switchboards or party lines.

Silly Sods!
Maybe it was just a local thing. It could be ptfe sleeving of course. Brian
Most likely someone just didn't have the right sleeving to hand.

I have found that white seems to colour used to earth appliances where there is heat, e.g. ovens.
I've found in the past that heat resistant green/yellow sleeving isn't stocked by my usual sources - eg TLC - so I confess to having used white.
