My sister once told something which I feel is very plausible ...

Something related to colours, that colours are different for different people... For example, what is yellow, looks what it looks like to me, but it looks red (my red) to someone else, but which that person calls yellow.. similarly what is green for me is green for everybody, that is, all of us call it green, but everybody sees a different colour.... what do u think ?

It's called - being colour blind.

No, read again, im talking something else..

Nope. Our eyes (and brains) are similarily constructed which means what we see should basically be the same.

A more interesting question (no offense) is what the world really looks like? A dog sees the world without color. A fly sees it in a different way. We see it as we do.

Who is right? No one or every one. What the world really looks like (if there is such a thing) is impossible to know.

your trying too hard OP

sure and what is freaky is that as we age our sense of colour/smell etc all drift.....

you fellas are not too bright hey? It's easy to test whether we are seeing the same color - even a 6th grader could tell you the experiment construct that would easily test this.

But all who are not color blind identify the colors the same even if my yellow is seen by you as red to me. We both agree it's a "Universal" yellow.

It is not possible to see a colour Yellow as green from another persons point of view. Because our brains are similar in construction and the wave lenght of Yellow will be the one every rain recieves.
However it is possible to see a different SHADE of yellow depending on the person.
We all see Yellow as Yellow but each person will see it in their own personal shade according to slight veration in brain structure.

That is why we all see exactly the same person standing in front of us but out interpertation of that person will be somewhat different.
What we will not see (as you are trying to say)is a dog as a human or a stone as a camel.
Your sister was on to something but she did not think it through

This is a pretty old idea OP, sorry.

The only thing for a normal human is subjective emotional feeling and memories triggerd by the colour will be slightly different. However because the brain and eyes are the same instruments what you notice as blue is still the same wavelength and noticed as blue by another normal human.

Could the ancient Greeks see the color blue?
