Was discussing this the other day, It's so interesting to think about.
interesting, but ultimately the answer is just yes. yes guys, we all see the same colors.
Doesn't have to be an alien, I have a cousin that can't feel pain. He can feel pressure and (i think) temperature, but it's never a negative sensation. Like his parents literally had to teach him to say 'ow' when he saw blood. It's apparently some disorder I can't remember the name of where the nerves just don't develop, it's not cognitive. It's actually really awful, most kids that have it don't survive childhood

[QUOTE=ZestyLemons;39642272]Not convinced until you actually name this 'disorder'[/QUOTE] Such disorder actually exists. Basically the receptors for pain are either missing or disabled somehow.
I love vsauce.
A friend of mine did a study on this for her Mastersdegree. They came to a conclusion that we probably all(except for the colourblind) see the same colours.
Rad.
There cannot be any major differences. We are dictated by our genome, and our genes dictate the way organs and patterns are formed. Not in an absolute way, but the function should stay really close in every individual. Wavelengths of yellow and green mixed make us perceive blue. Blue wavelength makes us perceive blue too. You cannot possibly tell me that it is purely coincidental. There are some things you cannot completely attribute to random. Yes, it [B]might[/B] differ by a bit, but not radically like you guys like to dream about.

[QUOTE=Dead Madman;39642804]I sometimes wonder this but when people also say to me that orange stands out I imagine the chances of their orange being the dark grey I know being very unlikely since it's a dull colour[/QUOTE] that doesnt even make sense tho bc dark grey is not a color, it's a low intensity value of white light. you can't jump from comparing color to comparing color, saturation, and value.

The main features of the disorder are lack of pain sensation, painless injuries of the arms, legs and oral structures, hyperthermia during hot weather because of inability to sweat, syndromic mental retardation as a result of hyperthermia, infection and scarring of the tongue, lips and gums, chronic infections of bones and joints, bone fractures, multiple scars, osteomyelitis and joint deformities, which may lead to amputation. Other common problems are eye related, such as infection due to the sufferers rubbing them too hard, too frequently or scratching them during sleep. In addition, patients typically lack unmyelinated and small myelinated nerve fibers in the dorsal root ganglion. Both are responsible for transmitting pain signals. In addition, patients' sweat glands are normal in both structure and function, though they lack innervations by small diameter neurons.[/quote]
snakes can see infrared too...that would be cool
Can blind people imagine things in their mind? Like picturing what they are feeling?
[QUOTE=igotwowhacke;39644127]Can blind people imagine things in their mind? Like picturing what they are feeling?[/QUOTE] what in hell a blind person dreams? just sounds, feelings? i saw in one of those discovery channel documentaries that a blind person dreamt once with snow and a train station. He was blind since birth and he said that he knew what white was and how snow looked, like pure or something.
I just realised that another person's colors could be all "new" colors compared to mine, instead of being flipped.
[QUOTE=Talishmar;39647572]I just realised that another person's colors could be all "new" colors compared to mine, instead of being flipped.[/QUOTE] No there isn't any new color because there aren't new stimuli. There is no such thing as everybody perceives different colors. Check my post before this one.
I agree that animals could see colours completely differently than humans, but I don't think It's possible that everyone sees colours differently, mainly because we are the same species, how much different can it get? I mean it could be possible that certain people would see different colours, but not the majority, there could be a disorder that would cause colours to change in affected person's perception, but it could not be diagnosed. Fun to think about anyway.
Even if you argue that it's more of a matter of how the brain interprets the visual information, instead of the photoreceptors. Wouldn't the whole thing be debunked by complimentary colors?
Wouldn't this ruin "style" that people use for clothes and painting and stuff. Surely you wouldn't paint a house pink, orange, and brown because they look white, tan, and black.

Someone posted a study a while ago where perception of colour was affected by the amount of words people had for colours, there was some tribe who had the same word for 2 vastly different colours, and when children from the tribe were asked if there was a difference between cards of these colours, they struggled to see any difference. I'd be grateful if anyone had a link to the study.
i thought about this myself and i believe i came to the conclusion that we probably all see the same color pallete mainly due the color yellow being universally somewhat difficult to see on a white background, whereas this is not the same for the color green, or red, etc. which would bascially mean we either have the same pallete or we have different palletes with colors that don't exist to other people
[URL]http://en.wikipedia.org/wiki/Qualia[/URL] Basically this. Really happy that people aren't just bombing the thread with typical materialist "YES OF COURSE BECAUSE SCIENCE EXPLAINS HOW EYES WORK" because if you believe that, you're missing the point of qualia
I'm most fascinated by the thing about apes never having asked a question and the Theory of Mind. And about colors, I think it's pretty safe to assume colors look the same to most people because we're all the same organism and we largely work the same way.
