No, the Germans used to use RED for earth. Add to that the fact that
red-green colour-blindness is quite common and the need to harmonise on
something other than the old British system isn't hard to see.

No disrespect to colour-blind people, but are they really the ideal
candidates to be wiremen?


I know of a guy who until recently was a TV service engineer and is red-
green colour-blind. When adjusting sets for customers he asked them when
the colour looked right for them.

And as for replacing resistors.... :-)

Takes me back to my schooldays - we had 3 physics teachers :

1 was red-green colour blind
1 was blue-yellow colour blind


and



the third was an idiot

Can you picture how resistor discussion went ?!?!?!?!?!?????
