We can measure the wavelength of the light (in the same way we can measure temperature) and say "that is what the mind interprets as blue" but blueness exists only as an idea.
Other animals perceive what humans call blue. So there is such a thing as blue. Don't discount third person/entity perspective.
Other animals perceive the image on TV as being three-dimensional, that doesn't mean that it actually is. And, actually, many animal species can be proven by an experiment to be color-blind. You just think they perceive colors the same way you do because of, well, qualia.
