Interesting link, thanks. My son failed two medicals for jobs this summer due to colour blindness, very frustrating indeed. My wife and my father inlaw are also colour blind and one day my son and father inlaw were playing snooker but they had a problem distinguishing the brown ball from all the red balls so, my father inlaw had to ask these teenagers on the next table to point it out for them, much to my sons great embarrasment. They haven't played together since lol


Cheers John
