Inverted Spectra, Philosophy of Mind: A term used to describe a thought experiment showing that we cannot be sure that stimuli (here light wavelengths) will be translated into similar mental states by all subjects. It is possible that a color is not localized at the same place on the color spectrum for all subjects, e.g. in an extreme case one may see something as red which another person considers to be green. Since the use of language is based on both having learned public language, they would use the same word despite their differing subjective experience. See also knowledge how, private language, qualia, skepticism.

John Locke on Inverted Spectra - Dictionary of Arguments

Chalmers I 263
Inverted Spectra/Locke/Chalmer: (Locke(1)): It would not lead to the falsehood of our simple ideas if the same object in the mind of different people at the same time evoke different ideas.
>Idea/Locke
.
Chalmers: for Locke it is about systems with the same behavior, while we are concerned with physical differently structured systems, even if they are functionally equivalent systems. This is possible in a conceptual sense. Question: Is it also empirically possible?
>Inverted spectra/today's theories, >Qualia.
