I could be completely out to lunch here but I recently removed the carpeted panels that cover the rear bulkhead on four different DeLoreans. The purpose was to make modifications to mount speakers on these panels. They were absolutely four different colors. One came from a black interior car and was closer to a charcoal color. The other three ranged from a silvery gray to a rather yellowish gray. The silverish was from a very low mileage car while the yellowish had seen considerably more sun. I suspect the history of the car accounts for the most variation at this time. Things like smoking/non-smoking, battery fumes from leaving a battery charger on too long, sun exposure as well as possible different batch lots of original material. There was a surprising amount of differences as well in the other materials used so they were obviously struggling with vendors and getting the production problems ironed out. I kept carpet samples from spots not exposed (back side wrapover) over the years and there was still conciderable variation, so I know it was not all sun induced color change. Hope this helps.
