Which color indicates pedestrian warning, bike warning, and playground warning?

Yellow-green is the color used to indicate warnings for pedestrians, bicycles, and playgrounds. This choice is crucial for awareness because it easily attracts attention while differentiating these specific warnings from other types of signs. The use of yellow-green helps to enhance safety for vulnerable road users, ensuring that drivers and pedestrians alike are alerted to potential hazards in areas where these activities take place.

In traffic safety, color coding plays an essential role in conveying information quickly and efficiently. Yellow-green stands out in the environment and is recognized universally for its association with non-motorized activities, thus promoting caution. Other colors have their distinct meanings that do not encompass these specific warnings, making yellow-green unique and appropriate for such purposes.
