As others have said, amber looks older. It contrasts, or maybe "clashes" is a better word, a bit too sharply with the car's color for many people's taste. I think there are several colors that are an exception to this statement; red, yellow, and possibly that aqua-blue. Black looks satisfactory with amber, but it looks tougher with the smoked lights.

Even on the smoked lights, when the lights are on they illuminate amber.

Plus, with the exception of headlights, it's a relatively cheap and easy to do mod. Even if you prefer amber, I think the red/clear tail lights make such a significant difference in the appearance of the 986/7.

Non-amber lights are/were available from Porsche, so could it still be considered original kegman?
