Original factory color is verified from the color plate on the driver-side door jamb by the B-pillar, or via the Porsche Kardex production record. Light Ivory and Black-over-Black are noted as desirable on SWB cars; many original greens (Conde, Leaf) have been repainted over the decades and become visible only in engine bay hints.
