You gotta be joking me 
3 nice easy distinguishable colours vs brown, black and grey. Even I can struggled to tell the difference between some of the blacks and greys without having them next to each other, and I ain't colourblind.

have you ever looked at a colour chart that they use for car paint? I have always wondered where you stop seeing a colour and it turns to something else.
Anyway, if you cant see any of the colour plates then maybe you should think about something else!
Good luck anyway!

Yep I'm afraid I have to agree.
The very fist part of my apprenticeship, before even being accepted onto the training scheme was a colour blindness test.
I don't know if this is still the case though, but I think it is a fundemental requirement for carrying out electrical installation work.

Okey dokey. Am a plumber but wanted to be able to legally fit kitchen/bathroom wiring without having to carry on sub-contracting (difficult time management on small jobs)
You've saved me the expense and arguments getting a refund after the college sales reps have told me "it won't be a problem sir!!!"

The questions I was asked before my DISQ course were:
1) What is your name?
2) Do you have £600?
Nothing about colour blindness, and there was no medical. I guess if people couldn't distinguish brown/blue/YG they would get picked up but there was nothing formal.
The change to harmonised colours was, as it says on the tin, to harmonise the colour schemes used in different countries.

That was a major factor in dropping green as cpc, as red/green is the commonest form of colour-blindness.correct me if i am wrong but i though one off the reasons for wire colour change was to allow colour blind people to be electricians

The ones on that website all have numbers - some are more readily distinguished than others but when I ran through the tests my times per image ranged between instantaneous and 0.5s....

I'm aware of the fact - have been through them with family members. Was being sarcastic.

Harmonised colours may well be easier to see for the seriously multichromatic colourblind, but will be of no real use regarding anti-discrimination until such time as there are no "old" cables in houses.
OK - didn't realise that.
Is there any evidence that brown/blue or brown/black/grey colour-blindness is any less common than red/black or red/yellow/blue?
I don't believe that colour blindness problems were in any way a factor in the decisions on harmonised colours...

I think it was more to do with red/brown that some old cables used to use - to remove the ambiguity, but you'll have to correct me here.
Also, the use of dual colouring for earth instead of plain green??
Somehow, I think I may not really be the right person to ask, for obvious reasons.
The most common form of colourblindness is red/brown/green, which means that when I watch snooker on TV, I cannot easily tell the difference between the reds and the brown.
