In my opinion one of the worst things was some equipment where aI

red was off and green was on. We got in some equipment from Europe and
they used Green for off and Red for on. The reason being that Green was
safe to open the door and red ment power was on and danger.

And just to further complicate matters, in domestic consumer units
nowadays, the spur is live when the switch is in the 'up' position and
'off' is down. This is arse-about-face to what I - at least - was brought
up with in the UK.
