Consider this issue in another way. Human brain is a huge computer
designed for pattern recognition. There's a difference between having the
scientific knowledge of colors and knowing about their existence and
having your brainware learning to do pattern recognition between different
light wavelength combinations.

The difference comes purely from the fact that doing the pattern
recognition for latter is a different problem from understanding the
differences intellectually. (And it is different, because thats how our
brains teach themselves). Nothing magical in here, nor is qualia needed
for this.
