Do we see the colours same as each other?

Question

Do two people see the same colours exactly the same?How do we able see colour?

Answer 1

your exquisite question is not as difficult as it seems.

consider first that a condition known as "colorblindness" occurs with frequency in humans. this ranges from total color blindness ( rare ) to partial red-green color blindness ( 8 % males ).

these people clearly cannot distinguish color the way the majority of the population does. ( experimentally testable ).

the ability to distinguish color has to do with the presence of certain nerve cells known as "cones". the quality and quantity of these cells vary in individuals ( e.g. colorblind people ) and thus can be equated to color perception.

although philosophically one can never prove that even normal individuals see the "same color", it is safe to assume that persons with the same composition of these cells "see" the respective colors in the same way.

there is NO reason to argue that you see colors any differently ( if you are normal ) than your parents since you inherited the same apparatus genetically. the argument that color perception varies dramatically among normal individuals is weak ( although untestable experimentally ).

even similiar colorblind individuals ( genetic twins say ) should perceive the same variations in light according to this argument.

the answer to your question is thus somewhat complicated.

in summary, i believe that individuals with similiar cell structure should see color in the same way ( e.g. blue probably looks "blue" in most normal non colorblind humans.). i am also saying that blue looks different in colorblind individuals but that it still looks the same amongst those individuals !

i hope more light ( and color ! ) was shed on your interesting question !

Answer 2

That's a very good question... Two people do not see the exact same colors. Take a dark blue for instance, one person may see navy, the other may see a violet. The signal path from the eye to the brain may have an influence, but it may be from habitual learning. Say, if a person's parent saw a color different and taught the child, then the child may misconceive the color for what it is simply by what they were taught. It's kind of like the idea that no two snow-flakes are exactly the same.

All I can say is 'probably'. Consider the automobile. All ford escorts are made the same way using the same materials, and they all (usually) perform the same, within certain tolerances. It's the same for biological systems. So yes, we probably do.

Of course, there are variances. Some people are color blind, or can't see particular colors or shades. Others have varying shades of perception, seeing things brighter than others. Some people can focus with their naked eyes so well that they can see the rings of Saturn. Variations are expected.

We see colors because the retina (back of the eye) is made of rods (for B&W) and cones (for color). As to exactly HOW they work is very involved, and in fact, most vision is done in the back of the brain rather than in the eyes. Fascinating topic.

Answer 4

This a good question and Brian in on the right track. The reflected wavelength is the same for all observers however the processing is uniquely different for each observer. The difference is not in a mechanism but in say sensitivity to detection. If we could measure and quantify the sensitivity then we could answer your question precisely. The skin sensitivity is another good instance to consider. Some are more sensitive then other to touch and sensing different textures. Most of as will agree which surface is soft or prickly but the measurements of ‘softness’ or ‘prickliness’ will be subjective.

Answer 5

The answer is NO. There are people having Daltonism, that see the RED colour EXACTLY as the GREEN colour. I had a colleague like that in the Army.

Answer 6

If people are not colour blind then i think they see the same shades.
However the effects the results have on people must vary or we would all like the same colours.
I honestly cant say i have known people to react in the same way to colours asi do.
I find this particularly true of colour combinations.

Answer 7

Some color blind people are able to distinguish some colors. Though their perception is not the same as that of a color seeing person. Therefore, at least some colors are probably not perceived in the same way by everybody.

You could probably say the same thing about hot and cold.

Answer 8

The question of if all people see the same color as the same thing is one of science's best known unanswered problems. If history's greatest minds could not conclusively determine the answer, I must humbly admit that I, too, am unable to.

As for how we see color, I can handle that one. Different wavelengths of light excite different photoreceptors in our eyes. A photoreceptor is a special cell inside the eye that responds to light. The photoreceptors that respond to color are called cones, and those that respond to light and dark are called rods. There are three kinds of cones in the normal human eye, one each for yellow-green, blue-green, and blue-violet light. Different combinations of these colors form all of the colors you can see. When each photoreceptor is stimulated by components of light in its own wavelength range, it sends a signal to the brain, where the signals are combined to form the image of the color they represent. Brian is correct that we see an object based on the wavelengths of light it reflects. For example, plants are green because chlorophyll reflects green light and absorbs all other wavelengths of light for use in photosynthesis.

Answer 9

This is more like a philosophy question, because no one can prove the answer. So far, no answer to this question. We see colours because the object absorb wavelength, and the wavelength DOESN'T absorb will reflect back to observer. For example, red apple absorb ALL wavelength but red.

Answer 10

not.

Sometimes are dissorder, like the daltonims, for example.
