Since this red-shift is used as a measure of recession speed the Hubble constant will be overestimated.
For example, galaxies that are more than the Hubble radius, approximately 4.5 gigaparsecs or 14.7 billion light-years, away from us have a recession speed that is faster than the speed of light.
Like the whistle of a receding train, the light from a galaxy is shifted to lower and lower frequencies - meaning redder and redder colors - the faster its recession speed.
