Again I am simply asking is the bus's surface the same red as I perceive and if so why?


No. The question is a category error. Pigment on a surface is not neural classification of spectra. How could they possibly be 'the same'? Are they well correlated? Yes of course. In that sense you accurately identify the bus as red. You can functionally discriminate like and contrasted colours.

So are you saying the red I perceive is not the same as the surface of the bus? How could they be? I am saying the same thing or at least trying to.
