what happens between neuron patterns emerging and me experiencing red, well, being red, instead of let's say blue for the same sensory input? where is the mapping, or are we all seeing totally different colors? even so, where does this information about the quality of this color come from.

The 'color' you experience is meaningless in itself. The feeling behind it is what's important and we see that it is often shared between social groups, but can vary between different social groups.

Why?

To keep you alive. If we associate red with danger, it doesn't matter if we experience the same color in our minds as long as our group associates the same physical wavelength.

The same goes for color experiences with much longer payouts. If you need to collect the yellow berries to survive the winter then having a qualia of enjoyment may increase our ability to survive.

Thanks for answering, but it seems like a utilitarian cop out, hand waving the problem aside. To keep me alive I just need to react to the physical wavelength, the internal experience isn't really necessary, sort of like reflexes. A robot can just as well be trained to react to red wavelengths detected by some sensor, but it doesn't have an internal experience of that color. I don't think it's meaningless.

So again, we're asking the wrong question. If you want your robot to 'experience' the color red, you must first train your robot to not want to die more than anything else while also putting limitations/imperatives on it that it must keep doing things to survive in the meantime.
