I think its more likely that different eye/brain sets might see the same colour very slightly shifted, one way or the other, on the spectrum. One person might see it a little redder or bluer than another. But, as we decided before, one can never really know. Its not the same as colour blindness. My guess is that normal human eyes all see the spectrum the same way and it is in the brain that differences might arise ... if they do.
