What color combination indicates an incendiary device?

The identification of incendiary devices is crucial for safety and appropriate response. The color combination of black writing on a red background is standardized to indicate the presence of an incendiary device. This visual cue is designed to be highly noticeable and easily recognizable, ensuring that personnel can quickly assess risks associated with the device.

The use of a red background serves to attract immediate attention, as red is commonly associated with warnings and danger. The black writing provides contrast and clarity, making it easier for individuals to read the essential information at a distance or in less-than-ideal conditions. This combination is leveraged in military and safety protocols to ensure a clear and effective communication of hazards.

Other color combinations listed in the options either do not correspond to incendiary devices or may indicate other types of ordnance or safety information. Hence, the specific pairing of black writing on a red background is tailored to convey the specific danger linked to incendiary devices effectively.
