A very...ummm...interesting point. But it does
not describe the creation of color. It describes
how the *frequency* of electromagnetic radiation
in the visual range is affected by relativistic
effects in atoms. Color itself is a subjective
sensation in the mind. It does not exist until
the radiation reaches the mind via the eyes,
optic nerve, and visual cortex.
