Stone Grey

Stone Grey (5710) is a historic Porsche grey with a distinctive greenish-beige or khaki undertone that distinguishes it sharply from conventional neutral greys — Rennbow notes it is actually less a grey and more a greenish-beige/khaki, and is surprisingly attractive in person, particularly when paired with a red interior. Porsche's official PTS documentation confirms it was introduced as one of the four original special colors for the 356A in 1957 under code 5710 (Reutter 710), alongside Orange, Auratium Green, and Glacier White. The color returned at the end of the 1960s for the 911 and 912 under a revised code. In 2022, Porsche presented the Taycan GTS Hockenheimring Edition in Stone Grey to mark the 90th anniversary of the Hockenheimring. Forum participants describe the paint as difficult to photograph accurately, with the greenish-khaki character shifting significantly depending on light — a shade that looks unlike almost anything else in the Porsche catalog.
