Which color is specifically used for warning signs related to pedestrian crossings?

Fluorescent yellow/green is the color designated for warning signs related to pedestrian crossings. This specific color is used to enhance visibility and draw attention to potential hazards, particularly in areas where pedestrians may be present, such as crosswalks. The bright hue is effective in alerting drivers to the proximity of pedestrians, especially in conditions of low light or inclement weather.

Using fluorescent yellow/green helps convey the urgency of the situation, signaling drivers to proceed with caution. This color is recognized for its association with increased vigilance around pedestrians, ensuring safety for vulnerable road users. In contrast, other colors like blue are generally used for informational signs, black is typically used for regulatory signs, and red often signals stop or prohibition, making fluorescent yellow/green the appropriate choice for pedestrian crossing warnings.
