  Depends on the rules being used. A likely scenario is that an additional tie-break would be used.
  
  For example, in the regulations for the [2016 US Championships](https://www.uschesschamps.com/information-2016-us-championship/regulations):
  
  > If both Players bid exactly the same amount of time, the Chief Arbiter will flip a coin to determine who shall choose their color.
