There is no color in the lifeless physical universe: there are only electromagnetic waves of different wavelengths (frequencies). But the marvelous human and some other brains have optical systems that perceive the differing frequencies as different colors.
There are two ways of interpreting this. Either that the enormously complex brain has the unique capacity to turn some electromagnetic waves into colors which simply don’t exist in the universe; or, that 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 paper or canvass or surface, color and meaning, order and symmetry are implicit aspects of the universe, which only the human brain (or similar complex structures) can actualize.
As I interpret the world, meaning and mathematics are intrinsic to the universe, but just as we can never become aware of double star systems or spiral galaxies without telescopes, one needs a brain to become aware of meaning and mathematics.
