The blue still exists. It's not perceived, but it still exists. Reality contains the human mind. The human mind doesn't create reality. I know that this sort of statement isn't popular with with the enlightened kids, but it can ceratinly be proven, as opposed to the meme that the human mind is the engine that supplies its own contextual environment (another word for reality...a bit more descriptive, but accurate nonetheless).

I'm trying to decide if we agree or not. It seems like we're saying the same thing but using a different definition of "blue," haha.
Regardless of whether or not the human mind can be said to produce its own contextual environment (c'mon--dismissing a very important--and, whatever you may say, unresolved--philosophical issue as a meme?), I still do not see how "blue" can exist independent of perception.
We *perceive* energy of a particular wavelength as blue. It interacts with out perceptive mechanisms to produce the color that we know as "blue." Sure, it can be reliably reproduced--but "blue" is only perceived when someone is there to perceive it (obviously). Without perception, energy of the appropriate wavelength does *not* interact with any perceptive mechanisms and is, therefore, not perceived as blue. It's tautological.
So I guess that that leads me back to my earlier claim. I ask, then, that you respond specifically to this issue:
I submit that:
(a) "blue" is a product of the unity of energy with a wavelength of 440–490 nm with a given (for our purposes, human) sensory apparatus.
(b) energy with a wavelength of 440–490 nm, divorced from perception, is not blue. "Color" does not exist outside of perception.
(c) energy with a wavelength of 440–490 nm still exists outside of perception. It is not, in itself, any different from that same energy united with a perception mechanism. "Blue," however, is not a property of the energy *in and of itself.* It is only a property of the union of that energy with a sensory apparatus.
I think that (c) is the most difficult claim to support--there's really no logical basis for the presumption that the energy really does exist when not being perceived. Assuming that it does, though, works well for science and "feels right."
Overall, though, I agree with you (I think). Energy with a wavelength of 440–490 nm can exist outside of human perception. Calling it blue, though, is just...totally meaningless. You cannot divorce blue from perception.
Concerning the claim that "reality contains the human mind. The human mind doesn't create reality."
You're right, in a sense. Reality does, in fact, contain the human mind. This fact does not magically give the human mind direct access to reality, though. The mind accesses reality through perception. Using the tool of perception, the brain produces a usable image. That image--the things that we see, hear, etc.--is not reality in and of itself. It is specifically the *perception* of reality. So, sure, the mind is a part of reality. That statement does nothing to support your broader claims, though. A stone is a part of reality, but it cannot know reality in and of itself. Human perception can be used to examine that stone. The "seen" stone and the "felt" stone are not the stone itself, though. They are the stone through the filter of perception and mind. So, in another sense, the mind, though it is a part of reality, "creates" its own reality based on the perceived outside world.
I am not arguing for solipsism here. The "created reality" of the mind necessarily emerges from a synthetic unity of perception/mind and "reality in itself." We can know, examine, and fruitfully discuss that union. We can neither know nor fruitfully discuss the "reality in itself."
Are we discussing terminology or reality? Just so I'm solid on what's happening here.
I refer to the conditions that come together to cause our visual systems to perceive the color blue, when I say that "blue exists".
We can't determine the level of perception distortion, but we can know that reality does exist, and that's what's actually being discussed in this thread. Not the true nature of reality, but the simple existence of it. Reality is whatever it is, and whatever that is, it's not dependent on our interpretation of it. If we can agree on that, then we agree.

That's what I'm still trying to figure out. I support the idea that energy waves of a particular amplitude can exist outside of human perception. Calling those waves "blue" is, in my opinion, nonsensical. Color is necessarily a perceptual property, so divorcing color from perception is nonsensical.
But you have redefined "blue" in a manner that removes its color-quality. The "conditions" that you've mentioned, as far as I can tell, include the presence of energy with a wavelength of 440–490 nm as well as the circumstantial conditions (temporal, physical, etc.) that allow it to come into contact with the visual systems. Essentially, you're adding some circumstantial conditions to the presence energy with a wavelength of 440–490 nm and calling it "blue." The particular circumstantial conditions that you assign to such energy to make it "blue" are those that will lead it to interact with visual systems.
Based on that, I see your definitions as such (correct me if I'm wrong--I'm taking the above quoted statement to the strictest literal sense, so if you were at all imprecise, this holds no meaning):
(a) energy with a wavelength of 440–490 nm that will never encounter a visual perception system: not blue.
(b) energy with a wavelength of 440–490 nm that will encounter a visual perception system: blue.
So now it seems that definition *is* at the root of the problem. I stick with the standard perceptual definition of "blue." It seems to me that you define "future blue" as "blue."
So, based on this, my main question is: Why have you chosen to redefine blue? Why is the inclusion of "future blue" into the definition of "blue" fruitful?
Without visual systems, the circumstantial conditions that come together to cause our visual systems to perceive the color blue cannot come together, so your redefinition of blue still relies on the existence of of a perceiving entity. By your own definition, blue cannot exist without an observer.
The claim that we can consistently reproduce "blue" does not support the notion of an objective "blue" that can exist beyond human perception. We can consistently produce things that reflect energy with a wavelength of 440–490 nm. Unperceived, these still are not blue. Replication does not grant an objective external reality to "blue," it merely means that we can produce things that reflect or project energy with a wavelength of 440–490 nm. Such things, if viewed, will result in the unity of perception and energy that is defined as "blue." By your redefinition, these things can be considered blue because they will, in all likelihood, be perceived. Again, I fail to see how such a redefinition is valuable.
We can't determine the level of perception distortion, but we can know that reality does exist, and that's what's actually being discussed in this thread. Not the true nature of reality, but the simple existence of it. Reality is whatever it is, and whatever that is, it's not dependent on our interpretation of it. If we can agree on that, then we agree.
I haven't reached the point where I feel comfortable claiming that there is an objective reality, but I have been taking the existence of an objective reality for granted when making my arguments, so we, within the confines of this discussion, agree on that point.
Again, we're clearly not discussing the same issue. I'm discussing the existence of blue and you're discussing the relationship between blue and the perceiver of blue. Existence and perception of that existence by a disinterested party are two very different issues. This becomes very obvious once you've let go of the traditional view of material existence.

Aah, alright. This is the origin of our disagreement. I think we are discussing the same issue, though.
I simply define blue as a unity between energy waves and perception. So, yes, I am discussing the relationship between blue and the perceiver of blue, but to me, you can't have one without the other. Your "existence of blue" is, at least using the standard definition of blue, wrapped up in my "relationship between blue and the perceiver of blue."
Existence and perception of that existence are certainly different issues, but both are necessary when one seeks to define a perceptual concept such as "blue."
So, accepting that our core definitions differ and probably will continue to do so--and that that is (probably) the heart of this issue--I have two questions.
How is your redefinition of blue from the standard perceptual understanding useful or valuable? What makes *unobserved* energy with a wavelength of 440–490 nm blue?

You are right, it doesn't. My point was that being at that level of intellect has more of a perplexing problem analyzing it than the average person. As this thread illustrates, there are those who would start reading through it and go "Whoa! That's over my head". All I was saying was that it is much more of a burden to those with genius level intellect to ponder and debate reality than it is for the average person. I wasn't trying to belittle anyone.
Perception is what color is all about, but its natural production occurs devoid of perception. In essence, a lone cardinal, stranded on a tiny island for its entire life, alone and never perceived, will still leave a little red corpse behind when it finally dies.
Birds use color for mating purposes, and other animals use color for protection and predation. Color is employed by flowers to attract bees. Color has many applications that predate the emergence of the human intellect.

Is there such a thing as objective reality? I don't see how it's possible. No matter what measurements are taken, they still have to be experienced and understood by me in order to be real. If I get punched in the face, it seems real to me. I experience pain and see blood. That's plenty real for me, and all I care about.
And when I die, reality will cease to exist. So good luck. I'm destroying everything when I go.
