what are your conclusions from this survey? i mean-- каждый охотник желает знать где сидит фазан
and i see half of the people wrote this. I'm hardly anything insightful.

Less than half, I believe. Which is incredible, since these colors are fed to children as 100% true for everyone. My personal hypothesis is that people who were taught this rhyme (or equivalent) as children will see these colors only, but people who managed to avoid it as children or, for some reason, rejected the authority, will see something entirely individual. See for elaboration: http://mme-n-b.livejournal.com/31364.html

Since these colors are fed to children as 100% true for everyone
Well, they are 100% true because, on a purely physical level these are the only colors that are produced by visible light of a single wavelength within those ranges and this is their order in the spectrum. This doesn't mean that someone may not think he sees some серо-буро-малиновый or whatever but this is as relevant as, for example the fact that some color-blind people won't see the green. Our eyes aren't a precise instrument and neither is our brain objective at interpreting what is seen. Fortunately civilization has developed some better tools than our eyes, which, together with repeated measurements by several independent and unaffiliated entities may help us construct something which is more like objective reality.

Sorry, but you are deeply wrong. An infinity of colors is produced. We see only a few of them. Some of us see more, some less (I know a person able to distinguish over 40 kinds of green). And - read the link about Aristotle again. There is no such thing as objective reality.

An infinity of colors is produced.
I have never said otherwise, but since, for example "green" is defined as a light whose wavelength is may be anything 490 and 560 nm, we put all of its possible shades under the category of "green." Sure, some people may distinguish more shades and some less but this still doesn't make the previous statement wrong or untrue. There is no such thing as objective reality.
I have read this and I both agree and disagree with that. I am perfectly ready to accept that different people see things differently, feel differently, experience differently etc. There is, however a certain framework that is common to all people, according to which two times tow is four, well-defined measurements for units of space, time and weight exist and they are common to all people (that is, unless we are going to realms of relativity or quantum mechanics, which i will deliberately keep out of this discussion). Color belongs to both of those realms and while different people may see colors differently, color is nevertheless something that is possible to measure exactly and that measurement, given the proper equipment, should not vary by something beyond negligible among different observers (and did I say we keep quantum mechanics out?). The seven colors that we know of course do not represent all the possible colors and sure, a better representation could be made with 16, 256 or 16 million. Still, the seven basic colors provide a good enough approximation to all the visible colors in the spectrum range. Now, I'm perfectly fine with the fact that someone may view colors differently and possibly see something like brownish magenta in the rainbow, yet i'm sure he'll have a hard time convincing people (even those who are not familiar with каждый охотник
) of this as a new standard.That is not to say that this personal view doesn't have a place. It does. It's called "art."
Tue, Oct. 9th, 2007 03:21 pm (UTC)
1. That's the point. Most people, having been taught to see "green" see only one color - green. And others see shades as diverse as "lime" and "moss". Most people can distinguish these two when not seen in a rainbow, so it's not the ability to distinguish them that matters, but the subconscious willingness to look for them in a specific context.
2. "well-defined measurements for units of space, time and weight exist and they are common to all people " Asch's experiments proved that these measurements, or, at least, our ability to perceive them, depend on authority.
"realms of relativity or quantum mechanics, which i will deliberately keep out of this discussion" Thank you!!!!!
" possibly see something like brownish magenta in the rainbow"
Forget magenta, that's to be expected. Notice the high incidence of independent sightings of black, grey, and white.
"i'm sure he'll have a hard time convincing people (even those who are not familiar with каждый охотник) of this as a new standard"
There is no standard, that's the point. A rainbow is as individual as a Roscharch test ;)

There are two separate things we're talking about, one of which is the physics of color, the other is its perception. We have, I hope, no argument about the former. As for the latter-- I do, of course, distinguish between the different shades of color that are present in the rainbow. I do not, however, name all these shades when looking at the rainbow. Why? Because they're irrelevant in this context. One of the greatest achievements of humanity is that of standardization and the seven-color model for the rainbow is pretty much a standard, which is based on science. It's not necessarily the best representation there is, but it is something that people can universally agree upon. As for our ability to perceive measurements-- well, yeah, there is a difference in that perception because of psychological reasons, but still, as long as we're keeping within the boundaries of classical physics, even though someone may think he had made an error in those because an authority says differently, it still does not invalidate the measurements themselves-- which, as long as they are carried out properly, within the boundaries of classical science should not vary beyond the negligible error margin between observers. The good thing about this standard and standards in general is that it is not based on perception, but rather on objective measurements and by objective in this context I mean something that does not vary beyond the negligible error margin between observers provided they carry the same measurements. There is, like I had said a place for those different perceptions in art-- it might be very interesting to see someone's picture of a rainbow with accent on brownish-magenta, but it is not something which should be universally used. Because if we want to do some scientific or engineering task which requires the use of color, we better have a model suitable for the task. Thankfully, there is a whole branch of science called "chromatics" which is devoted to just that. Perception of color may vary and if we put on green glasses we'll see the Wizard of Oz as well, but color in itself is something which is scientifically well-defined and objective.

"We have, I hope, no argument about the former"
Ix nadezhdy opravdalis' ;) I'm not nearly qualified enough for that type of argument.
"I do, of course, distinguish between the different shades of color that are present in the rainbow."
Are you sure? Do you truly distinguish between lime and moss, or merely know that they ought to be there? When you look at a rainbow casually do you see a distinct lime band and a distinct emerald band, in the same way that you see a distinct blue and a distinct purple?
"seven-color model for the rainbow is pretty much a standard"
China has more population than any other country in the world. Their standard rainbow has five colors and has had five since dim antiquity. Measurements, in this context, are irrelevant, (but, you are correct, reliable) since they'll always give you an infinity of shades. The way this infinity is broken up is a matter of consensus.
The five-color is not a better way to break up infinity than seven-color, although I can make the case for its being better than ten-color. It's just an agreed upon way.
Which brings me back to my point - standards depend on perception, not on measurements, and perception, in turn, depends on pre-set standards. I am trying to take a look at the perceptions of people who have different standards (pre-conceptions) than I do. In a way it's like arguing - even if you are convinced that you're right it's worth while to see different ways of looking at an issue.

I can see that the green gets progressively darker as we go down and so does every other color in the rainbow. I do not, however explicitly look for shades like lime or moss. China has more population than any other country in the world. Their standard rainbow has five colors and has had five since dim antiquity.
So they have a different standad. I am perfectly fine with the fact that there may be several different standards for something; it's not something out of the ordinary, on the contrary.standards depend on perception
Standards are usually chosen arbitrarily when they are set. It doesn't really matter whether we will use five, seven or ten colors for our rainbow model, as long as it is universally agreed on. As for your experiment-- I suggest that you ask the same people you did to name the rainbow colors again after a few months. I believe that you're gonna see differences and if after a few months you ask yet again the results will be different this time as well.
Wed, Oct. 10th, 2007 03:10 pm (UTC)
" gets progressively darker "
Precisely. A gradual change, not a band. Some people see distinct bands. It's this difference that interests me.
" I am perfectly fine with the fact that there may be several different standards for something"
But aren't you curious about the reason?
"Standards are usually chosen arbitrarily when they are set."
They are chosen and consented to for a reason. It's that reason that interests me.
"I believe that you're gonna see differences and if after a few months you ask yet again the results will be different this time as well. "
I am certain of it. The differences will be minor, but they will exist. Less than you think, though, since the question is carefully framed to be not "what do you see" but "what do you believe to be the standard" :)

A gradual change, not a band. Some people see distinct bands.
I think that this is not necessarily true and that most people do see a gradual progression of colors one into another; however when asked to name up to ten colors, they break and group them into ranges, each of which represents a particular color. I do not, however, have sufficient evidence (or any evidence whatsoever for the matter) to maintain this and might be totally wrong.They are chosen and consented to for a reason. It's that reason that interests me.
Well, length, for example has been defined in proportion to a ruling monarch's arm. Likewise, the colors of the spectrum have been defined by sir Isaac Newton, who said "this to this range is red and this one's orange." The reason, in this case is that he was there first. Reasons for standards may be diverse, but are usually based on stuff around us, which then evolve with then need for precision. For example, time had once been defined in terms of periods of celestial bodies. Now, the definition of a second goes like this:
"The duration of 9,192,631,770 periods of radiation corresponding to the transition between the two hyperfine levels of the ground state of the cesium 132.91 atom."
A really nice example though would be the reason for US railway gauge standard. The US standard railroad gauge is 4 feet 8.5 inches. Why was that gauge used? Because that's the way they built them in England, and English expatriates built the US railroads. Why did the English build them like that? Because the first rail lines were built by the same people who built the pre-railroad tramways, and that's the gauge they used. Why did *they* use that gauge then? Because the people who built the tramways used the same jigs and tools that they used for building wagons, which used that wheel spacing. Okay! Why did the wagons have that particular odd wheel spacing? Well, if they tried to use any other spacing, the wagon wheels would break on some of the old, long distance roads in England, because that's the spacing of the wheel ruts. So who built those old rutted roads? The first long distance roads in Europe (and England) were built by Imperial Rome for their legions. The roads have been used ever since. And the ruts? Roman war chariots first made the initial ruts, which everyone else had to match for fear of destroying their wagon wheels and wagons. Since the chariots were made for, or by Imperial Rome, they were all alike in the matter of wheel spacing. Thus, we have the answer to the original question. The United States standard railroad gauge of 4 feet, 8.5 inches derives from the original specification for an Imperial Roman war chariot. Specifications and bureaucracies live forever. So, the next time you are handed a specification and wonder which horse's ass came up with it, you may be exactly right. Because the Imperial Roman war chariots were made just wide enough to accommodate the back ends of two war-horses.

"I think that this is not necessarily true and that most people do see a gradual progression of colors one into another"
We are already agreed, I think, that most people see an infinity of colors progressing smoothly one into another. I'm more interested in what they believe themselves to see. :)
" the colors of the spectrum have been defined by sir Isaac Newton,"
In China? And Russia?
" Roman war chariots first made the initial ruts, which everyone else had to match for fear of destroying their wagon wheels and wagons"
I never believed that story, mainly because I do not think that an average road in Britain saw more war chariots than wagons.
Wed, Oct. 10th, 2007 06:46 pm (UTC)
In China? And Russia?
Sir Isaac Newton was the first person to conduct a *scientific* study of color and his model represents the *contiguous* range of colors in the spectrum. Now, is the Chinese model as contiguous? Or, given some shades from the infinity that exist in the range, a *chinese* person would fail to relate them to one of the five colors that are supposed to represent everything?I'm more interested in what they believe themselves to see. :)
and what are your conclusions about those people who see the rainbow differently?
Wed, Oct. 10th, 2007 08:46 pm (UTC)
"was the first person to conduct a *scientific* study of color and his model represents the *contiguous* range of colors in the spectrum."
I'm not trying to argue which standard is better. I'm saying that
a) there are plenty of different standards
b) most of them are not Newton's
c) I'm interested in understanding, not comparing them
"and what are your conclusions about those people who see the rainbow differently?"
Not nearly enough data as yet, but there are some things:
a) going to kindergarden does not help
b) having a dislike of authority does
c) being male improves your chances of seeing black and grey
d) being female improves your chances of seeing fine shades of blue and green

There is no such thing as objective reality.
No, there is.
Otherwise it would be impossible to build a computer.
