Exquisite luxury: Chestnutbrownmetallic is a warm and rich shade of brown with reddish undertones, named after the chestnut tree and its nuts. The colour has been available since the 2014 Los Angeles Auto Show, when Porsche introduced the Panamera Exclusive Series, limited to 100 units. Chestnutbrownmetallic is a medium to dark brown shade with reddish undertones that is used for a variety of purposes. The colour is a firm favourite because of its warm appearance and fullness, as it can create a feeling of cosiness.
