I am always complaining that they let the color blind guy draw the icons, but are they listening? Noooo....

Monochrome screens for everybody could be a solution.

Very true. I also had my share with these GUIs.
A lot of them are in the world because the developers who made it don't care about UI at all. They only made it because their boss told them that the software must be accessible for users also, not only for coders. They would make a command-line tool if they were allowed to.
And if there were any complaints by the users, then they will say: This user is too dumb.
Sounds funny, and in some way it is. But this really happens frequently.

It's kinda hard to see anything more than unrelated dots. However I do see a slight difference in color 
|
|
|

... When I have one eye closed while checking my work.
I always have to explain to people that one of my eyes isn't working so well on certain colours.
|

Wow, that's interesting! You're colour blind on one eye only?
I'd guess the colours mix when you view something with both eyes.
Is there a "stronger" eye, or do you see a combination of both, left+right, colours?
This statement is false.

It's mostly shades of red, orange, green or yellow that gives me trouble in my left eye. I'm not really "blind" to these colours, just that they appear very dull or "washed". Green in particular appears very dull. Though some shades of green do appear almost blueish.
My right eye is OK on colours and I don't really notice any difference when both eyes are open.
It may have been caused by genetics or some injury as a child.
I don't know of any others who have the same problem.

What could be the hidden "connection between IT and colour blindness"?
(Background: I call myself a software developer and yes my color seeing is somewhat deficient. So this question for my humble person translates to Why am I doing what I am doing? Where do I come from? Where will I go? What is the world about? And what about the fish? ...)
Ideas/opinions anyone ?

well, i dont think there is a connection between colour blindness and computer working...
What should be interesting would be to know the proportion of people having such colour blindness in the general population and to compare with the CP people

I have known several color blind people who find it aggravating that applications frequently rely on color to convey important information (e.g. red for errors.) If you can't distinguish between colors then the meaning is lost.
Therefore, I think that if you are designing user interfaces it is important to ask the question, how would this look to a color blind user.
As a side note, I find Color schemes generator 2 very help for designing color schemes with purpose in mind.

I have a colour perception defficience, what should i vote for ?
|
|
|
|

Colour blind. You are "blind" to at least one colour. Colour blind people don't necessarily see the world in B+W.
|
|

|

for me blind seemed "not seeing"
what if i see all colours but some switched ?

Dunno mate, maybe something like synthenasia?

Not that funny.
I have problems distinguishing between certain nuances of red, green and brown...
Well, not really a handicap to me, but I'm not allowed to become a forester or an electrician, if this thing with software development goes wrong.

You need to be able to judge a tree from the different shades of green its leaves might have...
When I was a child, the trees in my drawings often had green trunks and brown leaves. I think a forester should do something if he sees such a tree in reality... (No idea what, but for sure something.)

A friend of mine don't see difference between red and green. He is not allowed to be professional driver, however he has driving license (at least traffic lights are always in the same order  ).
Once he said the most annoying part of it is when he pays using credit card. He always hear:
"please enter your pin and press green button"

"My software never has bugs. It just develops random features."

He is not allowed to be professional driver, but he is allowed to drive for private purposes ?
I personally am not afflicted that serious: I reliably can distinguish a tomato from, say, kermit , but when it comes to buying clothes, I better have someone with me...

Exactly. It is one of the mysteries of life (or of law)

Eyes and laws are a curious couple indeed.
Same goes for piloting an aircraft: With glasses between -5.0dpt and -8.0dpt you are able to get a recreational (RPL) and private pilot license (PPL), but you must have better eyes for a commercial pilot license (CPL)  . You need almost flawless eyes to get a airline pilot license (APL), -2.0dpt max.
The only difference between a PPL and a CPL is that with a PPL only you yourself can determine your destination; with a CPL you are allowed to be told where to fly to.
To stear a little to the topic: with a color-deficiency you cannot get a pilot license, period.
