The color orange in X-ray analysis is typically used to denote biological materials and some organic materials. This color coding helps security personnel and analysts quickly identify what type of substance is present in the scanned object.

Biological materials can include items like food, human tissue, and other organic components that may be of interest in a security context. This differentiation is crucial for identifying potential threats and ensuring that the X-ray scanning process can effectively categorize the contents of bags, luggage, or cargo.

In contrast, high-density metals, electrical components, and gaseous substances are represented by other colors in the X-ray imaging process, allowing for a clear and organized system of identification.
