The idea of colour harmonisation is great, and the use of green/yellow striped for earth/CPC excellent as even a colour-blind person can identify the most critical wire to get right.
But the new phase colours were a rubbish choice as they are counter-intuitive. In nature all of the most dangerous animals (wasps, poisonous frogs, etc) make themselves bright to warn predators "have a go if you think you're hard enough?". The same should apply to cables. Ask most folk without electrical training to say which is the earth/ground wire and many will say brown as it is the colour of soil.
Can you get brown/grey/black indicator lights?
Rant, rant, rant, etc.
Still, sod-all we can do about such a long standing committee decision
