Seeing the world through rose coloured glasses?

[kawasakirider]

Like I said I cant explain it properly but there is a good Hypothesis on it. Not meaning its true but very believable when told by the correct people, that being not me haha.

Lots of things are believable when spun by a charismatic person. You'd be surprised.

Is it not how you have been raised/taught and the exposure to the things that you see determines the way its interpreted?Example: if you raised a child away from the outside world and taught it growing up that the colour red was actually the colour carpet and that fridge is actually a stickytape then im assuming they wouldnt know any different? is that the kind of thing you mean?

Well it is correct that scientifically we see the same way, it is perception that differs. For example, when two people see red, the light difraction that causes them to see red is the same but one person may see a bright happy colour, whereas the other may see an annoying, garish colour. Same colour, seen/perceived a totally different way. On another note, if there was absolutely no light would anything exist at all?

Speaking of tripping out, another thing to take into consideration is LSD. When people take it, they have a variety of different experiences, from tasting colours to smelling numbers, etc. So if our brains can get muddled up with our senses, it's not too far fetched to think that we may all see colour differently.
Even without chemical enhancement I can taste orange, and smell number 2's

I wish I was a religious man, explaining lifes mysteries would be easy... God did it.

Is it not how you have been raised/taught and the exposure to the things that you see determines the way its interpreted?Example: if you raised a child away from the outside world and taught it growing up that the colour red was actually the colour carpet and that fridge is actually a stickytape then im assuming they wouldnt know any different? is that the kind of thing you mean?

Thats perceiving from misinformation, I think this is how every one perceives a standardised thing I.E we all know something is the colour red but how the colour is perceived is different.

On another note, if there was absolutely no light would anything exist at all?

ahaha thats pushing a very philosophical ball park. But i believe we still have touch and smell so we can identify if something is there still.

Thats a good point, got me thinking now!

Ok, so let's say my green is the equivalent of your blue... Which is completely pollywollocks... But let's say that's the case... Why does it matter if we see colours differently?

For one... I can't even pass a colour blind test (Ishihara colour blind test)... I'm one of 10% or so of the world that can't see every colour distinguishably!

Or is it you who is colour blind and I actually see the colours correctly....

My biggest hate of colour blindness (actually one of two) is when I tell someone and if they don't say "Oh, what colour is this...?" pointing to their shirt or something, they instead say "So everything you see is black and white?"

(idiots).

Anyway... What it comes back to... In order to be green to collect energy from sunlight, plants all need to be a specific colour for chlorophyll to react with the sunlight. And this wavelength of light is incredibly particular...

Colour comes to us in frequencies (very high frequencies) and the eyes pick up those frequencies in specific orders and translate them... We pick up sound frequencies in much the same way through different channels and we can pretty much assume we hear the same sounds as each other.

We have similar reactions in other senses - so why would sight be different?

We're all pretty much made of the same stuff... Some things react slightly differently depending on our wiring - but over all the outcomes are the same!

The second reason I hate my colour blindness was it prevented me from becoming an air traffic controller instead I became a teacher.... Punishment much!!!

 

[gosia]

you have too much time on your hands lol )

In regards to teaching children isn't it the same as another language? In english red is red but in many other language kids are thought different names. But when asked, to them red will always be red (well unless you are color blind!) How the brain recognises it, well we see it we remember and then recall! I dont think that we see it any differently from one another. The brain might recall things a bit differently from one another eg. if I say dog - you might think of a chihuahua but I might think of a golden retriever but in the end still a bloody dog.

So I guess as long we all recognise green and red and know one means go and one means stop then we b ok.

I've always wondered about the hearing thing. I think it's probable that there would be variations in the way we each hear things.

We have similar reactions in other senses - so why would sight be different? But we don't, really. Lots of us are diverse in what we like regarding taste, sight, smell and hear. My GF is studying physiology, and did an experiment today with her class which concluded that some people thought that cucumber had a bitter taste. I certainly don't think that.

We're all pretty much made of the same stuff... Some things react slightly differently depending on our wiring - but over all the outcomes are the same!

The second reason I hate my colour blindness was it prevented me from becoming an air traffic controller instead I became a teacher.... Punishment much!!! That sucks! There's a movie with Steve Carrel, and this kid had taken a vow of silence until he got accepted into the army to be a pilot. On a road trip, his little sister had a colour blindness test, he failed and was devastated.

I guess it doesn't really matter, but I find it interesting. We can all just go on with our lives, or we can become consumed by philosophical thoughts. I prefer to keep a nice balance of both

Quick crash course in colour vision...

There are three human cone receptors, short, medium and long. These all have different peak spectral sensitivites however they overlap to a degree. So if you fire a red light into the eye it activates the 3 different cones at different amounts, with the L cone most excited and the brain then interprets these ratio's and you see red.

Now the M and L cones have reasonably similar peak spectral sensitivities with a lot of overlap and these peak sensitivities do differ in people in the population even between people with 'normal' colour vision. So people definitly can percieve colours differently.

Most people who are 'colour blind' arent really colour blind at all but are colour defective in that the gene that codes for there M or L cone is significantly different to normal. So there peak sensitivity(of the L and M cone) is different to most peoples and they may have trouble distingusihing certain colours.

The genes coding for the M and L cones are found on the X chromosone so males have a much higher rate of colour disorders at around 8%.

 

[viciousred]

Its something they can never even really test, Until they create a optical nerve interface that is... so in a few more years we will all know the answer, until then we'll just have to boggle our brains with the possibilities

and lol The brain is doing just fine thanks, apart from being splattered on a wall that is ;P

 

[KaotikJezta]

I think we do hear and taste things differently as well, even feel and smell. Some people love the sound of a certain song others hate it, some people like the taste of seafood others hate it, some people like the smell of roses, others hate it. Some people love the feel of velvet, others hate it. I have a friend who hates chocolate, I don't understand this at all, chocolate is awesome but she finds it disgusting. She hates the taste, the consistency, the smell, everything about it. It is all subjective.

I'd kill to have that problem.

 

[viciousred]

I second that

 

[snakeluvver]

I'd kill to have that problem.

Yeah I'd do anything to hate cake/chocolate/lollies. The only reason I stay healthy is Im active at school, but when I grow up I can see myself getting lazy and scoffing the biscuits on a reclining chair all day. So basically Im gunna get fat and obviously noone wants to be cos of the health issues ect

BTW back on topic - what exactly does colour blindness mean?

 

[KaotikJezta]

Just develop an overactive thyroid, you'll be right!

Little Miss Sunshine is that movie....

Back to your bitter cucumber taste...

I sometimes wonder if people even understand the meaning of the words bitter vs sour... Even Kate Nash suggested in her song "You said I must eat so many lemons, 'cause I am so bitter."

Acids are sour.. Citric acid (lemon's acid) is sour...

The pith is bitter (I agree) but generally a lemon would be more sour than bitter... And I guarantee someone will argue that.

It (unfortunately) begins to reflect on their general knowledge or vocabulary - it does to me mean they don't know what the two words actually mean!

Ok, - back to wavelengths and frequencies...

Our eyes pick up the wavelengths of light because of sizes of receptors... The same with hearing.. we pick up sounds because of the size of the receptors - the speed they vibrate at.

It is plausible there's some mild variations between individuals, but to think the variations would be large, significant or even that diverse would mean we'd need different modes of acceptance to these various stimuli.

It's therefore improbable that we see colours in many different shades (as far fetched as you see blue I see green but we call it the same colour). Therefore in conclusion - because cones and other sight cells are actually particularly manufactured for their purpose, much like a light switch, there may be some tiny variations in how they switch on, but the overall outcome is the same. The brain can pick up the colours based on wavelength - the colours are predetermined by their frequency and wavelength (assuming Einstein is correct with the speed of light) - the eye therefore requires specific sized cones to pick up specific wavelengths and the brain does the rest...

I agree, some MINOR differences will occur between individuals (eg colour blindness), but ultimately that does NOT indicate we see completely unique colours believing them to be that of an opposite colour.

Cones are specific to their purpose and that can not change... It's only the brain that can have it changed!

Incidentally - green is the most relaxing colour to the eye - red the least... That seems static amongst humans regardless of age and gender...

At the end of the day colour is purely a subjective response to difference's in wavelength. Some people will swear a car is blue while others will call it green. How the each person's brain perceives differences in wavelength is almost impossible to fully determine.

In the words of Erwin Schrodinger

"The sensation of colour cannot be accounted for by the physicist's objective picture of light-waves. Could the physiologist account for it, if he had fuller knowledge than he has of the processes in the retina and the nervous processes set up by them in the optical nerve bundles and in the brain? I do not think so." [SUP]http://www.aussiepythons.com/forum/#cite_note-Schrodinger1958-1[/SUP]

 

[Red-Ink]

Beyond the physical response of the human eye.... colour as a perception is a reflection of a specific wavelength/s of the spectum directed towards the human eye.

As our own eyes do not generate any spectrum what we see is reflectance from an outside source.... so at the end of the day a "blue" peice of paper can actually be seen as red depending on what wavelength is being reflected back towards the eye.... So what colour is it actually???

She hates the taste, the consistency, the smell, everything about it. It is all subjective.

its a matter of nature and nurture in the case of taste perception, nature as in some things we are inclined to prefer such as sweets (sugars) and fats, as they both help our predecessors survive and,well, do stuff.

kids have been shown to be more sensitive to taste, just because they tend to be more vulnerable to anything perceived to be toxic or dangerous (usually that comes in the form of bitterness)

supertasters have denser papilla and are more sensitive to flavours, a little can really go a long way for them

nurture wise, it's the things that you grow up with. Personally i absolutely hate vegemite, while i'd happily chow down on a durian, something most westerners would relate to having the smell of onions, sweaty gym socks and death with the texture of curdled milk. I just think of it as natural custard... mmmm....tasty

back on colour, i do believe there is a certain degree of opinion in stating the identity of something, example, one time a friend had these jeans which she said was really dark green... Well i thought it was just black, so we made a bet and asked one of the tutors to guess. She said black, but then again, what was the colour of those jeans? Perhaps there wasn't enough light reflected back? (cones need a certain amount of light to activate, rods on the other hand do fine in the dark) Perhaps one of us didn't recognize the colour spectrum as being one or the other? Too many variables to make a decision me thinks.
