I think this is a bit misleading. To the extent that your eyes can be thought to be trying to tell you anything, "these are different colors" is exactly what they are trying to say. It's fallacious to assume that there is some sort of "true" input that one's eyes are reporting, and which the post-processing stages corrupt. (I'm not saying you committed this mistake, but people might get that impression.) Instead the meaning emerges purely from the post-processing stages. In fact, they're doing a pretty darn good job, as one might note from the fact that optical illusions nearly never noticeably distort our judgment in natural conditions.
Yes, I completely glossed over the finer points of eye-brain interaction. I did not think it was needed to get the point across. I suppose I also used a bit of linguistic sleight-of-hand by implying the eye "tells" me things. I sort of just called everything from the occurrence of light leaving an object to me perceiving the light leaving the object as "The Eye."
If you can think of a better way to say it without adding a heck of a lot of complexity I am more than willing to edit the post.
I'm not sure if the eye-brain interaction is the relevant part. Even if you change "eyes" to "the visual system", the point of "these are of a different color is the very thing your visual system is trying to tell you" remains true.
What would you call it? The point remains that the colors are not the same. If we think the colors are the same, we are incorrect.
They are not the same, but our visual system is trying to tell us they are the same - and you can't really say it's wrong to make that judgment, as doing so leads to correct results the overwhelmingly vast majority of the time. (Basically, I'm saying the same thing as AndyWood's comment and the responses to it.)
Yeah, this makes sense. The trick is asking, "The same what?" The answer, "Color" is not descriptive enough.
I never meant to say it is right or wrong for the visual system to do whatever it is doing. I mean to say it is wrong to expect something different from the visual system than what it is doing.
"my optic system"? "my visual system"?
Optics system works for me. I changed a few of the sentences to use this instead of "eye."
Is it "optics system" or "optic system"?
*checks wikipedia*
Apparently it's either 'optical system' or 'visual system', and the latter seems to be preferred for organisms.
Updated to visual system.
