I'm going to refurbish the interior of my 1980 GMC Sierra, with new door panels, arm rests, seat belts and maybe dash. I would say the original (now very faded) interior color was some version of "tan". When I look at replacement parts from , Brothers, etc, the following colors are available (varies by supplier): tan, saddle, light buckskin, dark buckskin. Is there no consistency in these color schemes? I would like everything to match the best I can. Any thoughts?
