I think there was some island in the Pacific where the majority of the population had red-and-green color blindness. I'll see if I can verify that, find a source or something
yes, it's possible to imagine a color you've never seen. easily- by posing the question you're doing it. perceiving such a colour is something entirely different, however. you need to realize that nothing in the universe really exists as we observe it with our numerous senses- our mind imposes everything from color to depth. these colors certainly exist, and we can certainly imagine them, but we can not perceive them. thus, they are beyond our perception, yet we are still intelligent enough to acknowledge their existence. that's one of the few things about humans that is actually unique among animals.
Well that source was quickly found. Though only 10% of the population is affected. [url]http://en.wikipedia.org/wiki/Pingelap[/url]
[QUOTE=ThePuska;24462626]Yes, the way our brain generally works is very badly known. Difficulties already arise in strictly defining terms such as "intelligence", not to mention in explaining how it's achieved in the brain.[/QUOTE] Very true. I find it quite strange that the one thing we've ALWAYS had and known, the one thing we've only ever been sure about, the one thing we've USED to solve all of our problems (and some of them have been MONUMENTAL problems) in the past is the ONE thing that goes almost completely unexplained in its inner workings to this day. The big question is: why, and by what method, did consciousness arise? Not, 'why do we process and respond to stimuli', a computer can be made to do that. But why do [i]'we'[/i] [b]EXPERIENCE[/b]? Why is it that 'we' exist as people and conscious, sentient entities in the first place, and why is it that we're able to observe the universe? THAT'S the big question when it comes to the brain.
[QUOTE=Uberslug;24438867]This is not an uncommon idea, actually, but iirc there's really no way to know.[/QUOTE] Isn't it possible to ask someone if the color is darkish or lightish and compare it with what you see?
conceptually, yes. Otherwise, no because if we could it would be an actual color instead of a color that doesn't exist but can imagine.
You can't imagine what you haven't seen. I've talked to deaf people online, and they don't think with words like we do. They think in all pictures, hence why deaf people often make good artists. A blind person who can hear would think completely in textures, tastes, smells, and words, I.E: If they are thinking they are going to eat an apple, they wouldn't imagine an apple. They would think of the sound of the word apple, think of the smell, the taste, etc. They wouldn't imagine the colour or image of an apple at all. Our brain is a learning device, you are born with certain things in place but blind/colour blind people are born with a disability, so they never have that ability to "see" colour, whether it's through imagination or sight.
[QUOTE=Uberslug;24438867]This is not an uncommon idea, actually, but iirc there's really no way to know.[/QUOTE] I'm not 100% sure but I'm fairly certain this has been disproven, something about how our retinas perceive colors. No citation but I got that from a facepuncher so if he's around... :/
"Aside from the paradox raised when asking if you can know something that is unknown, the answer is No. The visible spectrum is fully accounted for. There are more than likely things in the invisible (to the human eye) spectrum that have not been discovered yet. One must know something about the physics of light and optics to understand it."
[QUOTE=Bran;24439066]yes, it's impossible. i'm fully colorblind and i don't know what these colours look like at all, and it's nearly impossible to describe without using terms like 'redness'[/QUOTE] Woah, your a gold member. :smug:
[QUOTE=st0rmforce;24438471]There's a guy who had the lenses in his eyes replaced with artificial ones. His new lenses didn't block UV, so he could see it. He said that it does look different to other colours, he was going to try to describe it, but realised that it was impossible. You have to see it to understand it.[/QUOTE] Wow, I'm jealous of that man, I want to know how it looks. [editline]06:16PM[/editline] [QUOTE=Master117;24439324]You can describe it scientifically. For example, pure blue has a wavelength frequency of 450 nanometers and each photon of light of this wavelength has 3.1 electron volts of energy.[/QUOTE] But you can't describe how you see it.

[QUOTE=ironman17;24438637]That's actually rather interesting. I doubt the strange colour would drive the man mad, although his eyes might get a bit more damaged from the UV exposure. I'm guessing that the indescribable colour that the artificial lenses guy spoke about would be similar to purple in a way, since it's in the same direction along the EM spectrum relative to the midpoint of our normal Visible band. Also, seeing through another person's mind or with another person's eyes might yield a different perspective. For all I know, I could be seeing one colour and perceiving it differently to another person. It's a bit too hard for me to describe.[/QUOTE] I've forever contemplated this. What if my red is the same as someone's blue, or my yellow is like someone else's green? Or what if my colours are unique, and no one else sees that which I see? And everyone sees it in their own way? It's interesting.
[QUOTE=ciniper;24438322]I was just thinking about this and I could Only really think of colors I've physically seen. Can anyone think of a color or shade of color that You've never seen?[/QUOTE] Not really. Our minds are built to percieve certain things; even if there was one we can't see, it would have to be somewhere on the EM spectrum, and we already kind of know those colors. Kind of. Unless you're stoned, then anything is possible. Edit: Cool, this is starting to turn philosophical, what with all the perception questions.
Ive got a nifty pair of lenses I bought at a trade show that let you see into the UV spectrum to an extent, pretty cool stuff.
[QUOTE=Master117;24439324]You can describe it scientifically. For example, pure blue has a wavelength frequency of 450 nanometers and each photon of light of this wavelength has 3.1 electron volts of energy.[/QUOTE] Oh, now I can totally imagine it!
Is it possible that my red for example would be someone else's blue or green?
[QUOTE=winsanity;24497043]Is it possible that my red for example would be someone else's blue or green?[/QUOTE] I've always wondered the same thing. Like if the colors I see are the colors you see too.
We ARE actually imagining a color: Magenta. [quote]If the eye receives light of more than one wavelength, the colour generated in the brain is formed from the sum of the input responses on the retina. For example, if red light and green light enter the eye at the same time, the resulting colour produced in the brain is yellow, the colour halfway between red and green in the spectrum. So what does the brain do when our eyes detect wavelengths from both ends of the light spectrum at once (i.e. red and violet light)? Generally speaking, it has two options for interpreting the input data: a) Sum the input responses to produce a colour halfway between red and violet in the spectrum (which would in this case produce green – not a very representative colour of a red and violet mix) b) Invent a new colour halfway between red and violet Magenta is the evidence that the brain takes option b – it has apparently constructed a colour to bridge the gap between red and violet, because such a colour does not exist in the light spectrum. Magenta has no wavelength attributed to it, unlike all the other spectrum colours.[/quote] [url=http://www.biotele.com/magenta.html]Link[/url]
