The speed of light is a physical constant. The frequency (or
wavelength) of a photon determines its energy and therefore, to the
human eye, its color.
Our ability to perceive light, and construct models of what it's
bouncing off in realtime, has presented interesting problems to many
noted scientists over the years. An illustrative example:
