I was specifically referring to the Color Experience. It would seem that there might be people that do not Experience the Color Qualia, but yet they have full Color differentiation. They are not Color Blind, even though they do not Experience Color (the Qualia). So I should have said they are Color Zombies, and not imply total Zombies. Anyway, I am still exploring this unbelievable possibility and am not completely sure it could be true. We have no way of Experiencing what another Mind is Experiencing. It is the inability or unwillingness of people to admit to having Color Qualia that raises this as an issue for me.
