In fact it's infinitesimal, since the electromagnetic spectrum is mathematically infinite (though I'm sure not physically infinite).
Having said that, I'm not really sure what your point is. There are actually an infinite number of different colours because the spectrum is continuous. That said, based on our biology and the fact that we see colours as a combination of three dimensions, then that allows us to see/conceptualize colours in a three-dimensional space. But that's specifically related to our physical perception of colour, and in theory you could have another species that saw it as two- or four-dimensional.
I don't think I'm disagreeing with you, just elaborating.

Actually, aren't there exactly three kinds of colour receptors in the human eye--one for red, green, blue? As well as rods for lightness/darkness. That's what I remember but that was a long time ago. I could have become confused along the way. :P

Additive: Cyan, Magenta & Yellow (although RGB will work, as well)
Subtractive: Red/Blue/Yellow
Actually the subtractive is Red, Green, Blue (wait isn't that additive and the CMY subtractive?). You can also use Red, Blue and Yellow as pigments, but only because blue is close to cyan and red is close to magenta, but they don't result in "proper" combinations.

Yes, you've been missing the brain 
A lot of color perception happens beyond the sensors. Why do we put color names where we put them? How much does that differ? There's an ongoing debate on how much this is cultural and how much genetic, and how much of the cultural part is linguistics.
One "teaser" can be found here: here[^]
some more[^]
Moooaaaaar!!![^]
But beyond that, the only thing I would like to add:
Wouldn't it makes sense to grant white full color rights for additive, and black full color rights for subtractive color generation?

Is there nothing free from political correctness?
The articles are interesting, but, they are referring to perception. The human basis set for colors, it seems, is roughly 'all the colors of the rainbow': about 6 or so for most cultures.
This part of the thread, oddly enough, was referring to PC monitors and how they created their colors. Human conventions, aside, we seem to be able to create our full perceputal set with a group of three.
An interesting though I've always had was - were I to see through your eyes - would I still call red red (etc.)? As long as we all look at the same color and give it the same name, we'd have trouble determining if we actually perceive them the same. Considering the poor taste in color exhibited by some, I'm beginning to wonder if they are mis-wired in their perception as compared to my perceptions (a.k.a., perfection).
So, in a nut shell - protestors may line up at my doors, but I will not give full color rights to black and white - nor those nasty little greys!

It was more about color definition correctnes, I don't know how Obama came in here

I wonder that, too. However, I'd wager a gues that the whole visual cortex largely needs to be rewired to see anything sensible at all, and during this reprogramming, color perception would also be re-defined.

Wait, you perceive colors the same way I do?

When you start seeing text in moving green letters after 13 hours of straight non-stop programming  ?

I had a similar experience. Except mine was a bit longer and I was in a hospital when I opened my eyes

Gmail has a cool "terminal" skin now so I see green moving text everyday. Sweeet!

For those afflicted, what do you feel when following this link[^]?
Male vs. female is probably the deciding factor why we peak above the average.

I think that the National average is 8% for men and only 0.8% for women. The 0.8% if probable for the ones that didn't understand the question!!
Why is it when you are busy everyone whats it yesterday, But when your not no-one has any work for you?

Slight irritation (Is this really something other than a hive of unrelated dots? You sure?). As if reality was behind a shop window - you can't get it but you're not sure if you have to anyway.
Well, we certainly will be above the average. That's because many colour blindness/weakness issues are genetically related to men only. Women simply can't get them. And AFAIK by far the most software development people are male...
- Or are these "8%" mentioned already men-only? Otherwise, it would seem a bit high to me... -

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 ?
