Imagine buying your dream car, picking your favourite colour, and then being told you cannot drive it because the paint itself is illegal. Sounds unbelievable, right? While most people assume car colour is just a matter of style, several countries have surprising rules about which shades can and cannot appear on public roads. Some colours are reserved for royalty or emergency services. Others are discouraged because they reduce visibility in harsh weather or create confusion during emergencies. These unusual regulations show that a car's colour can sometimes be about much more than personal taste.
