Is the radiation with frequency of 650THz (blue colour) decoded the same way in brain between different people? Could it be that what is my brain's blue is your brain's red? But we all call it blue because that is how we were taught by parents looking at the same object, while in fact experiencing a different thing in our brain.
It is possible, however such a concept is unlikely given the universal acceptance of color groupings such as fall colors, pastels, jewel tones, etc. Further, if my sky were red instead of blue my sunsets would be much less spectacular. My sunsets are spectacular therefor the sky cannot be red.
Alternately, how might one describe a color one cannot see?
