Physicists tell us that solid objects are really mostly empty space with tiny particles moving about (or at least, that is what they said a few years back). That is not how I experience my dining room table.
As for the color words, they are ambiguous, in that sometimes "red" means particular frequencies of light.
Sure, but we still operate from the framework --- when reconstructing the history of the planet, or the solar system, or the universe, for example --- that there are macroscopic structures that exist in the same manner as perceived by us, even when no one is around to view them... I'm just trying to figure out what they might appear like, if color is only a subjective phenomenon.
Color is how things appear. That is, to beings that are not colorblind. Without a perceiver, there is no perception. Of course, none of that means that there are not frequencies of light without something perceiving them.
