Porsche Convertible Tops : BMW Seat Covers : Mercedes Leather Seats : Soft Top : Porsche Carpet : German Auto Tops Inc.
The colors/shades you mentioned are very different and IMO aren't very complimentary...but that's ultimately up to you.
Virtually any quality upholstery shop close to you will have sample charts and/or swatches. Or, use the link above to get to German Tops & Interiors to see their color charts and request that they mail you samples. The owner, John, or son Armen, know Mercedes cold and are quite helpful. Good Luck-
