I mean it like it is explained in answer 4 of your second link:
Colors are defined by wavelengths, and when there is an apple that reflects red light, that is what everyone sees, no matter what they call that color or what it actually "looks like" in their heads.
Obviously the human mind is rather imaginative and converts something as simple as light of a certain wavelength into a concept of color. Add to that all the emotional associations.
One problem in this discussion is that color can mean different things, in the other link for instance it is used both for the perception of wavelengths (what we think we see and refer to with words) and for the wavelengths themselves, i.e. the merely physical definitions.
With hearing things are a bit simpler, I think. For instance, what aspect of sound would people with defect hearing confuse or ignore (like color blind people do)?
