Why the colours we use (Brown/Blue/Green+Yellow)

Duane

I think i've flipped up

I was under the impression we use the Brown Blue and Green/Yellow help with colour blindness (most common green and red)

I know it's to bring UK in line with EU. But why did EU use them colours.  

Because I understand green earth (CPC)

Red Live (line) [hot colour]

(Forgive any misspellings Dyslexic and hard to see , also miss out works as forget to type them)

    I haven't seen any complaints when the colour of the Emergency Stop sign changed from red (under BS 5499) to green (under BS ISO 7010) back in 2012. (The latter making far more sense, as green is supposed to mean "the safe thing to do", "the safe path", "to make it safe" etc.

    If i google "emergency stop sign" half are red and half are green, despite nearly 10 years since the change. Wouldn't make much difference to red/green colour blind people admiittedly, but at least they haven't tried to change the colour of the stop button.
