When it comes to core racing colors, silver and Germany go hand-in-hand since the pre-war Silver Arrows days of Mercedes-Benz and Auto Union. And though Porsche tends to lean towards the original german racing color of white in more recent years, there's no doubt that its classic 1950s racers predominantly went silver. And one of the most popular modern Porsche silver colors is GT Silver Metallic (gtsilbermetallic; metallic UNI; M7Z / U2; Porsche).
