I had a Rallye Gold (actually sort of mustard yellow) Opel GT that I called Gandalf the Gold. Later a Porsche that was the color of a Chinese red pepper (like in Sichuan dishes), so that was Pfeffer (German word for "pepper"). My first Subaru was Yama Yagi, Japanese for "mountain goat." My current Subaru is Pommy because it's the color of pomegranate arils.
