Interesting discussion, I didn't catch the start so I apologize if I repeat what others have said.

Well I don't know about neurological efficiency, but it seems that evolutionarily speaking it might be advantageous to have a non-zombie reaction to pain stimuli. First of all, pain stimuli are often associated with situations where you need to flee or fight, in both cases the body needs to be in a fairly high metabolic state; elevated heart rate etc. Second, it seems advantageous to be conscious of pain (i.e. be able to think about it) so that one can figure out why one is in pain. That way one can avoid similar situations in the future, or one can choose to ignore the pain if the situation requires. |> Why this rather than that may again answer to what is |> most advantageous and most efficient: there is some sense to |> experiencing blue as darker than red, since it *is* darker; |> so inverting blue and red might weaken other cues of the experiential |> feel, other uses.

This reminds me of the experiment where some guy wore image inverting goggles for an extended period of time. After a week or two the world seemed right side up with the goggles on and upside down with them off. His sense of up and down eventually returned to normal after he stopped wearing the goggles.
