Manufacturers of cars use exotic colour names but I'm sure there is a real world equivalent that is much more accurate. Most car makers even trademark their colour names.
Dolphin Grey - Pigeon Grey
Pirates Black - Tyre Black
Cosmic Latte - Hearing aid beige
Deep Bronze - Turd Brown
Diamond White - White
Bright White - White
Laser white - White
Ivory - Dirty White
I'm sure you can come up with a few more.....
