The (current) view of physics is that there is no color in the life-less physical universe: there are only electromagnetic waves of different wavelengths (frequencies).
But the marvelously wonderful human (and some other) brains have optical systems that see the differing frequencies as different colors.
Now there are two ways of interpreting this:
1. The enormously complex brain has the unique capacity to turn some e.m. Waves into color which simply doesn’t exist in the universe.
2. The universe has two quite different kinds of characteristics: The physically tangible and the physically intangible. The latter are latent dimensions of the universe, which only a complex system like the brain can render explicit. Somewhat like a painting that simply cannot come into existence without a paper or a canvass or a plane surface, color and meaning and order and symmetry are implicit aspects of the universe, which the human brain (or similar structures) alone can actualize. According to interpretation (mine) meaning and mathematics are very much intrinsic to the universe, but just as we can never become aware of double star systems and or spiral galaxies without a telescope, one needs a brain to become aware of these.
What we sometimes call an emergent property is analogous to the “emergence” of pulsars when the sky is scanned with a radio telescope.
