A Tricky Question
-
If the colors we see depends on our eyes, what causes our eyes to interpret what we see is the color green, and many shades of it? :confused::wtf::confused::wtf::confused::wtf::confused::wtf::confused:

I am red/green color blind, but I still see 'green'. There is no way of knowing if my green is your green, any more than we can tell if my perception of a banana's taste is exactly the same as yours.

Our eyes do not interpret anything. The rods and cones in the retina react to the photons hitting them and send a signal down the optic nerve which runs postero-medially towards the optic chiasm. This is where information is relayed to the visual cortex, while other axons terminate in the pretectal nucleus and are involved in reflexive eye movements. The visual cortex then processes the signals to provide the image. This[^] link may help.

Then we're programmed by common sense to build a function which returns the name of the color whenever we see it.

Good job to all of you! :thumbsup::thumbsup::thumbsup::thumbsup::thumbsup: But just to let you know, I wasn't asking a question because I didn't know the answer, I asked it to see how many people could give the correct answer; and you all passed with flying colors (pun not intended). :laugh::laugh::laugh::laugh::laugh:

Dalek, this is not true at all. Our eyes do perform "pre-processing" of the signal in the most tricky ways. This is done in the layers between the rods and cones and the optic nerves. There is a lot of experimental data about it and tons of literature. Also, colors and other aspects if perception are subject of considerable individual variations. Some of those variations are clearly measurable; there is a lot of experimental data and literature. The concept of color and the concept of "normal" color perception is extremely complex. Light of different spectrum is perceived as the same color by one individual, but another one can see them as different. This is not because they have different sensitivity, but because of different "color balance". I want to emphasize that interpretation if vision signals is done not only in brain but also in the eyes themselves. I learned some of this during introductory courses into major specialty and later due to my interest to the topic. I don't say it was serious study, but I've read number of articles. Experimental techniques are quite non-trivial and not so easy to follow.

I think you were approaching this from a philosophical perspective, don't worry, I get you. Check this out[^], it's actually a big unanswered question in Western philosophy. It's a question of whether the colour (i.e. what we see in our own personal vision) is a product directly of the wavelength, or more of the mind assigning that wavelength a visual interpretation. Either way, you can still teach someone what the colour "blue" is, because all "blues" have the same wavelength. Trippy, isn't it?? Confucius say "red is only a colour, but green is a way of life" :)

A man of much wisdom, I believe he also said (in his capacity as a marriage counselor) "foolish man give wife grand piano; wise man give wife upright organ".

I certainly would not recommend the recent movie about him. Not Fat Chow Yun's finest hour.

I imagine that acting like the taskmaster of the group is also a good way to get one-voted.

You would be surprised to learn how very cunning experimental techniques can measure those differences; they are mostly based on field contrast methods… It's well known now that every individual has distinctly different "color balance".
