I would still differenciate between: “Does the brain map the Physical World to custom signals, or will it add something to it, because its not possible to see both”
Edit: I meant spectral color and nonspectral color.
There is still a meaningful distinction between spectral and non-spectral colors as far as I (a non-scientist) is concerned: what one is saying is “this is my perception of a specific wavelength of electromagnetic radiation” and non-spectral colors are “this is my perception of some kind of weird interference between opposing colors or a bizarre trick of the brain or whatever”. Color as such is still a purely mental phenomenon but what instigates that phenomenon can be different.
