There were a few things painted Parchment, the metal headliner side trim pieces and metal (on some cars) A pillar covers. Those items are painted on mine. As far as a dye formula you could find a local paint supplier that mixes dye and take a Parchment piece for them to scan and (attempt to) match with dye.Are you meaning the vinyl dye? Nothing was painted parchment. The metal dask, steering column etc were painted black.
