Which of the following is NOT one of the colors used in triage?

The color white is not utilized in the triage system commonly employed in emergency situations. Triage is a method used to classify patients based on the urgency of their need for medical attention, particularly in mass casualty incidents. The color codes typically associated with triage are red, yellow, green, and black.

Red signifies immediate care needed because the patient's condition is critical and life-threatening. Yellow indicates those who require urgent care but are stable enough to wait a little while longer. Green is used for patients who have minor injuries and can be treated or transported later. Lastly, black denotes patients who are deceased or whose injuries are so severe that they are not expected to survive given available resources.

Since the color white is not part of this established scheme, it correctly identifies an option that does not belong in the list of colors used in triage.
