Wouldn’t it be cool to somehow create a device that could measure this?  A color can’t really be doing the exact same thing in every brain, ja?


Of all the qualia discussion that has gone on for decades here, none of which I understood, this discussion may have triggered a trace of insight.  The same red may create slight differences in chemical responses in the brain which operate on very certainly different neural networks, to create an effect all the brains will agree is called red.
