Agent White is the code name for a herbicide used by the U.S. military in its herbicidal warfare program during the Vietnam War. The name comes from the regulatory requirements of identifying each container of the various herbicides through the addition of colored stripes. Orange, Purple, Blue, and White were colors used by the manufacturers to ensure that the contents were easily identifiable in shipment and use. Colors were selected by the U.S. Government. Largely inspired by the British use of herbicides and defoliants during the Malayan Emergency, it was one of the so-called "rainbow herbicides".
