Only in a known incorrect Newtonian view of the Universe. What is
visible
light to you may be infra-red or ultraviolet light to me depending on
how fast and in what direction I am moving relative to you. It is over
95

The concept of visible electromagentic radation is distinctly more fuzzy
than you presume.
