How do we know that we actually see the same colours?

Question

Is it possible that different people could see colours differently? Could you and I both look at the sky, both knowing it is "blue", but what you see is a colour that I would call red (for instance) and what I see is a colour that you would call green and yet we have both been taught that that colour we see is called blue. A matter of perception. If that's the case, it could also be the true for the rest of our senses.
Hope that wasn't too deep for most of you.

Answer 1

An excellent question, and not just someone trying to get their homework done by someone else. There are three hints in humans that humans may see colors differently. Partial color blindness: some people cannot distinguish between certain colors, such as red-green and blue-yellow. This can cause many colors to appear different. Brown is 2 parts yellow, 1 part red, and 1 part blue. To a red-blue color blind human, brown would appear identical to orange or green. But still we do not know what they actually "see", we just know it is different than the general population. Drug alteration: we know that certain drugs alter color perception. But we still do not know what is "seen", just that drugs have changed the signal. Third, there are individuals that see different colors out of each eye. This is usually due to an injury and not genetics. Genetics usually affect both eyes. However, there is no report that a blue sky is red in one eye and yellow in another, or than a green tree in one eye looks purple out of the other. This is the closest hint we have that individuals may perceive different colors one from another.

Answer 2

I am green and red blind. I don't know if this means that if everything on earth was green and red I would be blind, but I do know that I can see a colour that I was told is red, and that it is definitely not the red someone who is not colour blind can see. In other words a mixture of the colours I am able to see have taken over. What I am trying to say is, at an early stage in your life someone pointed to something and said that is red, that is how you know it's red. If everyone you have ever met had pointed to blue and called it red, it would have stayed in your mind that way and you would be calling blue red, because you wouldn't know different. Simply, I it's just that have a smaller range of colours and mixture of colours to choose from.

Answer 3

An awesome question. Too often people forge that we don't see with our eyes. We capture impulses with our eyes but "see" with our brain. Its like saying you see what the camera sees, but really you see what the TV shows you. Why the same signal can be tinted or brightened. Our minds are a mystery. You ask a great question though, simply association is the answer. We know that differnt people proicess shades differently, some people can't see colors at all. Some people have a great eye for color. Maybe it is that we just agree that green is green. But if we could some how see through another's eyes (or brain) we would call it another color.

Color is subjective. I once took a pill that did change my perception of color...or did it make it right?
I thought about it till my head hurt, & figured out that it is one mass illusion, & will never be able to figure it out.
Tylenol helps!

This was Stacker II I took for 4 or 5 days, & I was so concerned I went to the eye doc. He sent me to the opthmaologist, & I had a brain scan done. While they did find a brain, they didn't find anything wrong with it! They could have sent me for more tests, but the opthamologist suggested that it was a fat soluable chemical & to wait it out. For a month & a half, the sky & grass didn't look like it had changed, but most man made colors all looked MUCH more vibrant! I had a small child, & his toys almost hurt to look at! I work in the printing industry, so I thought I knew colors! That threw me for a loop!

Answer 5

While we might not see EXACTLY the same exact colours, we wee them close enough to be accepted as the same. If one hundred strangers all witnessed a light blue car run a red light and crash into a red car and then the light blue car drove away, almost every witness would be able to tell the police that a light blue car ran the red light. They all saw the basic colours that the majority of us call light blue or red.

Answer 6

We absolutely see colours differently. In fact there could be a difference between your eyes in the way they perceive colour.

Try this experiment: Get a pair of those red and blue 3D glasses and wear those for a few minutes. Then take them off and look at your surroundings one eye at a time. Your eyes try to adjust for colour negativity, so each eye will appear to have a different tint.

Answer 7

Leaving out the color blind, we see the same colors. How do we know this. Because we can describe what a color looks like. For instance, we can say that green and blue are similar, red and orange are similar, and we can tell that yellow is a light color, and that purple is a dark color. If green to someone else looked red, then they would disagree with us if we said that green was similar to blue. If yellow looked like brown to someone else, then that person would disagree with us if we said that yellow is a light color. Unless you are color blind, people can agree on which colors are light or dark, and we can agree on which colors are similar to other colors; this is plenty of proof, but there is also more that can be said in describing colors.

Answer 8

you're extremely sensible to ask this question. I even have 2 solutions for this question. a million. so which you think of each physique see the different hues and refer it with an identical call. besides the undeniable fact that it fairly is very impossible. ok enable’s take a small attempt you. Take 2 hues like crimson and white blend them the two. What you get? You get the colour purple. And ask some one else to combine an identical hues and if he says the respond is purple then all of us see an identical hues and refer it with comparable call ok it became and unscientifically solutions. So under is the finished definition of ways and why we see hues. 2 colour originates in mild. solar, as we become attentive to it, is colorless. particularly, a rainbow is testimony to the certainty that each and all the colours of the spectrum are contemporary in white mild. As illustrated interior the diagram under, mild is going from the source (the solar) to the object (the apple), and finally to the detector (the attention and innovations). a million. each and all the" invisible" hues of solar shine on the apple. 2. the exterior of a crimson apple absorbs each and all the coloured mild rays, aside from those equivalent to crimson, and reflects this colour to the human eye. 3. the attention gets the pondered crimson mild and sends a message to the innovations. so as that advise apple is crimson for each human in this earth and each human refers it with “crimson colour”. I had given you 2 proofs that what we refer is what we see. ok i like to solutions this manner of question in case you have any extra this manner of questions save posting i visit be happy to respond to it. whats up i've got been given your question and study my answer heavily onse back and each sees the appropriate collor and refrense it with comparable call. i provides you lots proofs for this once you're nevertheless not stisfy with my answer digital mail me i visit clean your all doubts

Answer 9

There are variations from individual to individual in the absorption spectrum of the color dyes in the eye. Although small this results in slight differences in perception.

Various levels of color blindness most certainly result in diferent people observing different shades of color. This can be quite subtle (as seen in the test pictures at the eye doctor's office) or grosse when an individual is missing one color completely.

These sensory effects are specific to color where physical differences explain different perceptions.

Answer 10

No, its not possible, we all have the same genetic makeup, its not possible for us to percieve something in a different color because everyone has 99.9% same dna. Which means we would all see the same color. Whichever that color would be. Also your question is flawed because you inherntly assume that the name associated with the color is the correct identification. People could have named blue gorgigan and then you would assume that is the correct name to the color, it doesn't matter what the name is given as long as you see the same color. All eyeballs work in the same way. Except for color blind and blind, which are defective.
