If you only make use of the 3rd person scientific view, "colors" - as experiential, not as an abstraction - don't exist.

I don't really understand why it's so difficult for so many to understand this. We're taught somewhere between age 10 and 12, in our basic science classes, that "the apple is not "really" red - it' just colorless vibrations that are interpreted as "red" somewhere - we have absolutely no idea as scientists - in the brain."

if you follow that through all physicalist accounts of experience and consciousness, you'll realize that whether you call it naturalism or materialism or physicalism, it's a completely incoherent way of understanding science.
