As of 2015, DuPont does not make its paint color codes available; however, PaintRef.com provides a cross-reference for auto paint. The Historical Color Library also provides a search tool for DuPont colors.
At PaintRef.com, users can find particular models and makes of cars and their corresponding color codes. For most of the cars on this website, there is a corresponding DuPont color code and the color codes of other major paint manufacturers.
For Historical Color Library users, finding a DuPont paint color code requires entering the makes and models of cars into a search field to retrieve the results. Alternatively, a user can browse for color codes for foreign cars, domestic cars and trucks.
