The correct answer is: Yellow

Warning signs are typically yellow because this color is used to convey caution and alert drivers to potential hazards ahead.

This color stands out against various backgrounds and is a widely recognized standard in traffic signage, reinforcing safe driving practices. Red, green, and blue are designated for different types of signs, such as stop signs, directional signs, and informational signs, which serve other specific purposes on the road.
