If you can't answer the question the way I asked it, then there's really no point in continuing. You're misinterpreting the qualia concept in an effort to believe a certain thing about existence. My question was aimed at isolating this misinterpretation. Qualia are individual subjective perceptions. There is no 'qualia of redness'. There is a qualia of when I perceive a particular red thing, assuming qualia exist, that is. That qualia cannot be compared or contrasted with your qualia when you see another red thing. But the instant you take that out of context, what you're dealing with is no longer qualia. There's no such thing as a 'redness' qualia.

We can isolate red as a wavelength of EM radiation because of this.
