A common color for a fire truck is red. This vibrant color has been traditionally used to make fire trucks highly visible and recognizable, ensuring they can be spotted easily in emergencies. The choice of red dates back to the late 19th century when fire departments began painting their vehicles this color, partly inspired by the notion of bravery. Over time, the tradition has continued, and while some fire departments also use colors like yellow or lime green for high visibility, red remains the most iconic and widely associated hue for fire trucks in many regions.
