    im a newbie(a student) in science n tech... but sometimes i get strange doubts...i hope ull understand my doubt

    my doubt is.. the color what a person sees, is it the same as another person sees it?

    what i mean to ask is..for eg: i see a color.. say white.. and my eye sees it in a format say X, and if another person sees white ,will it look like X itself or something else..

    people identitify a color by name..but not by a format. from our childhood we call a particular format by a name..but is it same in everyone's view?

    i dont know how for u can understad my doubt...and also i have no (very very less) knowledge abt science...i hope u people help me..dont u

    The colour's people see are different depending on the person.
    Our eyes determine the world around us and different people see in different ways.

    First of all a colour is just a frequency of light and different frequencies give rise to different colours, White light is a mixture of the colours of the rainbow.

    The problem is different people may see different colours. For example both people may see a red object but may argue over the shade of red.

    Colour is picked up by photsensitive cones in the retina of the eye.
    I'm not really up on my physics of the eye, check out the following website:- http://hyperphysics.phy-astr.gsu.edu...colper.html#c1

    hope this helps

    yes, and liek a good radio.. and a bad radio.. the station comes in fuzzy depending on the radio.

    colour is there. but i suppose if you grow up thinking blue is green .. and green is blue, then until someone else corrects you .. you wll see blue as green or green as blue! but what if someone thinks blue is red... and red is green... and green is blue!!! like einstines relativity, it varys! but it is all the same, in the sense that the frequency is the same!

    as for the retina, if your color blind, then you see most things as grey, so in that sense.. blue is neither green nor red.. but grey. but the eye detirmins what you see....

    (cross referance..) back to the radio.. if the radio is good.. then you will hear bryan adams(the artist of choice!) perfectly. but what if a big mountin gets in the way? then it will change, and then what if your hearing is not so good. it will change format again:

    form perfect <-moutin-> fuzzzy <-hearing-> Y?

    now Y can be anyting, perhaps you hav ea ringin in your ear.. yoyu will hear byan adams with the ringing and fuzzy,

    but perhaps your ear blocks the fuzzy frequency! either its two hight.. or low? then you might go back to a sort of perfect? (say.. perfect1)
    so if your seeing red as grey? and someone points out that;s not actually grey.. its blue? Because they are refering to what they know it as?

    i know.. longpost... but it was fun.. and youi know why the above are even talke about?
    becasue we are intellagat. we see evey possibble angle! we cant jsut see the colour.. we need to know if the color is the color? is the color a good color? is the color there ? or just a reflections .. of a reflection? and is the reflection a reflection of a different color.. and its somthing else <- like a colourd bottle? -> jsut changeing the relfection?

    wanna know bout reflections? :P

    yup, i used the grey as an example, i was really guessing, and said grey for effect,
    i think its.. if you have no colour cells on the retina, then you depend on the black and white, and if you do.. you see colours wrong :?

    thanks fr all who replyed.. but my actual question was can people see diff. colors(but they might specify the name of the color same) on a single object without having any blindeness.. cell problem..etc.
    but since colors are just freeq. of light.. i think every one sees same..
    thanks again

    I know exactly what you are talking about, and I know several people who have wondered about that.

    Yes, a specific wave-length stimulates the three types of cones in the retina in a specific manner. I do not know if studies have conclusively proven that the cones are stimulated in the same manner in all people, or if that has just been assumed.

    But I think your original question was, even if crimson stimulates everyone's cones in exactly the same way, do you actually experience, or interpret, crimson as I do, or do you experience it as I experience periwinkle? Or even as a color I can not even imagine?

    I can not think of a way to test that.
    Why do they want us to believe Conspiracy Theories?
