There is no such thing as ’green” in the physical universe (obviously). It has no explanatory power, it has no causal power, and there is no viable theory of how it can be produced by other things (e.g. by light of whatever wavelength, since my experience of light of that wavelength could be different than yours). Yet, we know that “green” exists. Therefore dualism.
