Where is the blueness or the redness, if this and only this is the reality?
I already explained how blueness can arise: you have to distinguish between kinds of data, and your phenomenal experience of blue, is your label for the kind of data that is blue. Just as a program can use generated symbols to distinguish two kinds of data, you can distinguish between red and blue, or between sight and sounds, by being able to notice distinct traits about them that resist deeper scrutiny at the usual level of operation.
