Yes
Colour blindness is a problem I have, and as statistics say that 1 in 200 women and as many as 1 in 12 men have the same problem, is anyone else prepared to admit it and is there anything that can help.

Personally I find my colour printing is perfect in every b & w image I turn out, can't say the same for my colour images :(:(

I have been better able to see the colours using one of the lights intended for people suffering from SAD (Seasonally Affected Disorder, I am not a sad photographer!), is there anything else?

My main problem is red/green deficiency - at least at close range I can see red and green, even if not the same as people with "normal" colour vision, but further away the colours just blend together to a brown mush.

Any help would be appreciated, thanks.

I student of mine is daltonic (colour blind). I spent some time with
her to explain how to use the grey card to produce pictures of inte-
rest and quality for the viewer. A very affordable solution is the use
of the neutral grey card (or white), and must be use systematically
for every new light condition.

Since she can't be sure of what is recorded, the grey card becomes
the reference. At her screen, the same reference is used to apply any
WB correction prior to conversion.
 
Thanks Kodiak, that is one of the strategies I do use, absolutely invaluable for portrait work.

I had an X-rite Colour-checker but it didn't help me, though I know that if I used the software solution provided with the card that the colours should be correct.

I guess I lost faith as I could not see those colours.
 
Red green here also, black and white as you say OK. Am going to try a colour chart for setting shots on screen and then my expert colour proofer for print checking; my wife.
 
Same here, as you mentioned David, very common in men and something I learned when I was a H&S Officer and probably a lot of men don't realise they are colour blind.. For me now, although I don't print much I need to rely on my wife for colour accuracy. Perhaps I also need to purchase a white/grey card.
 
Thanks for your comments Guys, I now know that there are at least three of us!
 
Same here, red/green 'colour blind'. Doesn't often cause me any real life problems, but of course is an issue with any colour processing work. Fortunately the missus is usually on hand to help when needed. Curiously whenever I've taken those online colour vision tests, I score pretty well. But if I take the proper colour vision tests, my colour sight deficiencies show up.
 
Red/Green here, haven't had a major issue with colour printing but maybe no one has said it to me....
 
Our 3 sons have this condition but in the main have "learned" the colours. They learn these for themselves though and I suppose we all see colours differently. Reds/greens are the most common as many of us know.

On a tiny note, near us is a vivid green Jaguar car - really bright green, and for car enthusiasts not that flattering if truth be told. I happened to ask our youngest what colour he thought it was and he said bright pink! (Shades of green/shades of red.)
 
...and that is the problem!

Plenty of red/green deficiency about, and seems there is no solution (except mono!).

There seemed to be some specs that sorted the problem (they were designed to help diabetics find their veins when they needed to inject insulin), and they also helped people with colour-blindness to pass the standard Ishihara tests (circles of coloured spots on which people with normal colour vision could identify numbers). The specs are good for this, but all they really do is alter the colours you can see, not correct them, and they also introduce a strong yellow cast.
 
Well, I don't believe there is going to be a fix as such, our eyes simply don't have enough colour receptors for red and green. Can't fix what isn't there.
