Germans had brown for earth!

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.... :-)

'I know a guy' ... for reasons that don't concern the story;-
The Navy had arranged at great expense to demonstrate
a piece of kit to two of us, the other guy -call him Dick-
was _exceptionally_ quiet during the demo. As the jolly
matelots switched on this and selected that to indicate thus,
Dick remained shtum ... while driving back, I commented;-
"You were quiet today, Dick?" He responded; "I'm red colour-blind
and couldn't see a thing!" Every monitor, LED, legend and
read-out was red - to Dick's eyes, the Jacks had been playing
with a totally dead piece of kit!
