A color code is unlikely to appear on a Harley Davidson; often only the color name is listed. The code can be determined by Harley-Davidson. If there is no color code, the relevant reference is the PPG or Dupont (Axalta) paint formula number. Finding a code on the bike is uncommon, so identification typically relies on Harley-Davidson or, failing a code, the PPG or Dupont (Axalta) formula.
