PR4 signifies a specific shade assigned to vehicles manufactured by Dodge. This alphanumeric designation serves as a precise identifier for a particular exterior color finish. For example, a classic Dodge Charger restored to its original factory specifications might require verification of its original hue using this code to ensure accurate replication.
The implementation of such codes is vital for maintaining the authenticity and value of vintage automobiles. Precise color matching is essential for collision repair, preventing mismatched panels and preserving the vehicle’s aesthetic integrity. Historically, these codes have provided a standardized method for communication between manufacturers, suppliers, and repair facilities, streamlining the paint selection process.
