Well, technically speaking yeah you're right, but my brain is aging and I haven't used the term EGA in over a decade. So it's all VGA to me, muwahahahah! But, nevertheless that's what his joke was about.

No it's correct, you're comparing apples to oranges if you want to get caught up in how many colors we can perceive compared to the point I made - which was there's more than 3 or 4 colors in our visible spectrum and the color space examples you used do not mean there's only 3 or 4.

No - I'm trying to stay on topic (a little) - which is color-blindness.
However, going back to the much more enjoyable off-topic nature. If you refer back to the EM Spectrum, than there's an effectively infinite number of colors. Or, more correctly, the number of colors depends upon how good your cutting tool is when you try to seperate them.
A really really good diffraction grating (no one uses prisms anymore). may allow you to resolve the electronic discrete transitions (and then you discover all the black spaces bettween the every changing colors of the rainbow). And an oscillating emf around the source and they fatten up and merge. In this view, however, the number of colors is only limited by the diversity of electronic transitions that occur that fall into the visible spectrum AND then convolute that with the electromagnetic fluctuation (if any) in the environment (we're staying atomic - so rotations and vibrations are mercifully ignored).
In a way, our disagreement is philosophical. I am taking the perceptual perspective - where we actually have 'color'** - and you're taking the more physical perspective wherein each resolved wavelength is a discrete color.
(Please excuse my technocretia* - In real life I used to do laser photochemistry when lasers had to be built from parts and not ordered on-line.).

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

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!

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?

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

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
