On the common sense view that qualia are the kolors generated by our minds, which do so based on sensory input about the colors in the world, it makes sense that color-to-kolor conversion (if you will) should be imperfect even among people with properly functioning sight.

Its possible my writing wasn't clear enough to convey this point (or that you were objecting to CCC, not me), but I was getting at the idea that we probably do experience slightly different kolors. It was never my intention to be philosophically "rigorous" about that, just to raise the point.
