Nonsense Rose even those with cones that are faulty in some way still see the shadings of the various hues that they can see, plus it's rare to have complete colour blindness across the whole of the spectrum.
None of us can see ultraviolet, infra read and understand how radio telescopes work but I would think most of us are able understand how they work and what they are.
Another thing is explaining colour blindness can be demonstrated to most people with at least a half of a brain, would be able to understand,with diagrams etc, where as mythical, magical and superstitious nonsense is not and cannot be supported anywhere with diagrams or anything else, nor is it rational.
I had a jacket that was fawn to my eye apparently everybody else described it as green, so obviously they were all wrong.
Please note I particularly referred to the mythical, magical and superstional parts of various beliefs, because this is so often overlooked.

No ippy, you are wrong.
He cannot tell the difference between a pillar box red sock and a obvious laurel green one.
It's not a matter of degrees.
It's not rubbish, he is just an extreme example and according to an optician quite possible.
I've had chance to discuss it, as my son has inherited a more normal and not so extreme version.
My father can see blues.
But he cannot distinguish between red and green at all. ( just varying shades of grey)
My son is more subtle and fails the colour blindness tests.
My father is extreme and unusual. He has often worn one red sock and one green sock and that's why he would ask ( while saying of course he knew, stubborn he is)
The trouble with you ippy, is you are inclined to dismiss everything you have no experience of. Which doesn't make me value your judgements on religion.
No optician ever told me I was talking rubbish when I took my son for eye tests and they asked if colour blindness ran in the family.
I guess, unlike you, they knew what they were talking about.
My father is actually that extremely colour blind. It's rare, but not unheard of.
Me and my mother have lived with it for years.
