Can we prove the colours i see are the colours you see ?

I mean, i have always been told from birth that yellow is the colour of a daffodil, but can i be sure that what i recognise as yellow others do not see as what i would call green?

Can we prove the colours i see are the colours you see ?
I've thought about that too. There's no way to prove one person's perception is the same as another person's. All we can prove is that we all call something red.



The chances are that, due to our anatomy being made up in pretty similar ways, we actually do see something similar but I can't think of any way to test it.



Perhaps a difference of perception is what triggers different people's likes and dislikes in colours.
Reply:My son is red/green colour blind, he can see colour, and I never knew until he was 18 and failed a colour blind test for the forces. We went through the whole what colour is this stuff and he said that he sees red and green, but as red and green are to him, it is difficult to try to explain to someone how you see colour. When I worked with someone who was blind and wanted to know what colur was like we used cold for shades of blue, red for hot and various degrees of heat and the smell of grass for green. seemed to work. doesn't answer your question I know, but suppose you could ask a number of people what they see as yellow and green and go for the average.
Reply:yes just ask the other person wat color is he seeing

ofcourse u two should have the same perceivings



now that applies for all u compare
Reply:there is no way, to prove it, i asked people this question, not on here tho, ages ago, they just ended up getting confused



the only thing that U can find out is if someone is colour blind, but U can not tell if what i see as green is the same as Ur green, it could be purple. if i see the sky as red, and i'm told the the sky is blue then everything i see as red i would call blue, as long as i saw every colour differently then no one would ever know
Reply:nope, i might see blue but it could be yellow to you. who knows.............
Reply:Perception of color is often subjective, which is why in science, colors are defined by their wavelengths, so there is an actual scientific standard for constitutes yellow versus green. Often scientists will use what is called a colorimeter to analyze substances, in order to eliminate the subjectivity of perception of color. It is also used by people who are colorblind.
Reply:go and see an optician your colour blind
Reply:NO
Reply:There is no way to prove something like that because no one else can use your eyes or your brain except you.

but it doesn't matter because when I say that something is red you know that it won't look green to you.
Reply:Well sort of, we can prove what the colors should be, but different individuals could perceive them differently.
Reply:No, and this is a question that I have asked for years.



I think that there is now way to prove that the color green that I see is the same as the color green you see. It is all about how the brain interprets the reflection of the visible UV spectrum through the optic fibers inside of the eye. It is very subjective, and since we teach that each color has a name, there is no way to test the brain for differences in stimulation when different people are presented different colors.
Reply:Colour is the UK spelling.

I think you've picked one of the really funny questions that we all ask from time to time. Perhaps it isn't so daft when you consider that some men are colour blind. I don't know for certain that we see exactly the same colours, however, we must all see them in relation to each other in the same way.
Reply:easy way to solve this hold up a card that you think is yellow, show a number of people it and ask them what colour they think it is...bet they say blue just to pickle you're brain though...

ttfn ;o)

oh and make sure none of them are colour blind!
Reply:yes - however it would mean removing your eyes and measuring the colour receptor responses.



You could also use colour tests in which you are given a number of coloured blocks (i.e. different shades of yellow, to white) and you have to arrange them in order - the same would then be done for other colours...
Reply:I think you're right. We cannot be sure that others see or experience colors the same as we do.

As a matter of fact, I think everybody sees colors differently.

I believe that because I myself see a clear difference between my right and left eye. Especially the color red I see slightly but clearly different with one eye from the other.
Reply:I have always wondered that question,
Reply:yellow is yellow r u a colour blind
Reply:If everythings are yellow, I cannot recognise as yellow.

If everythings are white, I cannot recognise as well....
Reply:ahhh, the theory of other minds.

well, it has been troubling people for hundreds for years so good luck solving it.

luckily we have language to help us understand more
Reply:well i ive never thought a daffodil is green its yellow

is it the same as a banana lol

paint a daffodil and ask people what colour they see it will be yellow .





itkelsysop colour is uk way of spelling color
Reply:I may actually be seeing blue as yellow but as I have been taught that colour is blue it is not blue to me forever. What you may see that blue as is beyond me, however as you said, this colour stays constant and therefore that is now blue. So then I can ask what yellow is?
Reply:no, you can't prove it.



You can show a quantifiable measure of the wavelength of light (ie 600nm is 600nm), but individual interpretation of it may vary.



You could also conduct an experiment where subjects pick a color standard that they believe is identical to a test subject. From that you could derive the variation in perception between individuals to a standard.
Reply:Where are you from? I love the way you spell color. But, I have always wondered that same thing but when I ask other people they seem to think I'm crazy. But I don't think we see the same colors.
Reply:Scientifically, everyone has the same rods and cones in their eyes, which are used to detect color. (The only exception are people with disorders, such as people who are colorblind.) So why would we take in different wavelengths of light when our rods and cones are all the same? So, in other words, no, what you call yellow is what I call yellow, and so on.
