  • Patent number: 7337162
    Abstract: A computer implemented method for matching paint on a vehicle, having the steps of receiving in a central computer, from a remote terminal, vehicle identifying information relating to a specific vehicle and a first set of paint color data from a portion of the body of the vehicle. The central computer includes a processor, an electronic storage means in which a database is stored. The database includes vehicle identifying information for a plurality of vehicles, paint color data associated with respective vehicle identifying information, and paint formulations associated with paint color data. A first process by software in the computer determines a first best match paint formulation which relates submitted vehicle identifying information and submitted paint data to a paint formulation. The software in the computer determines a first best match paint formulation which is transmitted to the remote terminal.
