SEAT is the source to determine the paint color code, obtainable by calling SEAT. If a color code is not available, the specified alternative is the PPG or Dupont (Axalta) paint formula number. This indicates that color identification comes directly from SEAT; when a code is absent, the PPG or Dupont (Axalta) paint formula number is provided instead. In short: color code from SEAT, or PPG or Dupont (Axalta) paint formula number if none exists.
