What color is typically used to represent caution in a safety sign?

Yellow is the color typically used to represent caution in safety signs because it is highly visible and easily recognizable. This color draws attention and alerts individuals to potential hazards or changes in conditions that warrant increased awareness. For instance, yellow signs are often used in construction zones, around machinery, or in areas where there may be slip and trip hazards. The brightness of yellow serves as a warning signal, helping to prevent accidents and encourage individuals to proceed with care.

In contrast, other colors like red are used to indicate danger or stop, green represents safety or go, and blue is generally used for informational signs. Thus, yellow effectively conveys the message of caution, making it a crucial color in safety protocols and signage.
