This no real "white" in the universe either. White as we experience it is unique to our particular mechanism, in marriage with our ability to experience subjectively. And yet-- with 100% certainty I can tell you that the printer on my desk is white. I'm not sure I'd even say that it is objectively so, even though it is only through experience that "whiteness" comes into existence at all. Nor would I say white is a "euphemism" for multiple frequencies of photon when they combine in our senses.
That an experience doesn't map to materials or material processes doesn't make them "euphemisms." Love doesn't map precisely, nor happiness, nor probably any other subjective experiences. You would say that mind itself is a euphemism for certain kinds of brain function, I think.
It is clear that in our way of looking things, there is an interaction between brain function and mental experience. But your view that there are physical layers upon which the mind supervenes is kind of like insisting that one way of the globe is up rather than the other: it's not arrived at by discovery but by definition.
