But even lightwaves are illusionary and dependent upon our
  biological systems.

  We "see" colors, I believe, as a survival mechanism perhaps.
  Whatever the reason, the spectrum of waves we see is quite
  narrow. There's more that we don't see than what we do see; and
  THAT'S only the things we're capable of measuring.

  We're only capable of measure things that we can analogize or
  "map down" to the colors we can perceive. We can't see Infrared.
  But we can bring it into our color spectrum or otherwise, bring
  it into a form we can utilize, such as numbers.

  But even our equipment for detecting light is based upon analogy
  to our visual systems, extended further higher and lower and the
  information is compressed and brought into a form that we can
  biologically use and understand.

  Perceiving the bouncing of light; what of a species that did not
  see color but instead could perceive a more finely grained
  structure than we are capable of?

  No light waves necessary; the bouncings might or might be there
  for them but of no import.

  Perhaps they could see through more of a finely grained
  perception system that utilizes neutrinos as its basis.

  Neutrinos pass through solid matter; barely interacting with
  matter. A species that perceived through use of neutrinos rather
  than photons would not see colors at all but something entirely
  different.
