Here are some pictures I found once (this is NOT my car) .. I downloaded them because they were similar to the look I was trying to get of parchment with black highlights(carpet).

The images above have faded parchment parts.
Here is my current interior:

The difference between the top car and my car is (besides the seats obviously) is the kick panels. Looks like parchment panels were the "more correct" choice. But I had speaker/black ones, so I stayed with mine.
My car originally had some gold/ivy carpet that I Hated, thus my direction toward black carpet, thus why I found the kept those images.
Hope that helps.
