| Quote | | PS: On redness. Your dismissive objection obviously is rooted in the exchange with BD. Actually, as was pointed out [there was someone in my dept doing this sort of work as research], this is eminently definable empirically, as has been done for colour theory, foundational to display technology, printing, etc. It tuns out to be strongly based in reflection and/or emission of light in a band from a bit over 600 nm to a bit under 800 nm, depending on individual [there was someone else in the Dept who was colour blind], lighting conditions, and the like. Redness is an objective, measurable characteristic of objects, and being appeared to redly is something that can be empirically investigated once we are willing to allow that people do perceive, can evaluate and are often willing to accurately report what they experience. |
Some sock might want to ask him whether the diffraction grating atop Crawford Hall at Case Western is objectively blue, objectively red, or objectively green:

Or just ask him about magenta.
