What color commonly indicates the inner core of a detonating cord?

The inner core of a detonating cord is commonly indicated by the color purple. This color is utilized specifically to signify the presence of a high-explosive material within the cord. The choice of purple helps in quickly identifying the nature of the substance for safety and handling purposes, especially for those trained in explosives and demolition operations. The standardization of colors in such applications is crucial for ensuring that personnel can easily recognize and act accordingly when dealing with potentially dangerous materials.

Other colors such as red, white, and pink might represent different types of materials or applications within the field of explosives, but they do not specifically denote the inner core of a detonating cord in the same way that purple does. This color-coding is part of the safety protocols to reduce the risk of accidents and ensure efficient communication among those working with explosives.
