Tucked inside a declassified 1945 OSS memo — written by Acting Chief of the Field Photographic Branch Lt. John S. English, summarizing a March 21st meeting in Major Jeffries' office — is a half-page paragraph that reads less like wartime tradecraft and more like a movie pitch. The Office of Strategic Services, America's WWII intelligence agency and forerunner to the CIA, was operationalizing skin dye.

"In FETO the principal use for items of this kind would be in the form of skin coloring which would [disguise the appearance] of white men when they accompany natives on missions so as to make them less conspicuous and reduce the possibility of being an outstanding target for the enemy. This skin coloring program is under the name of 'War Paint'."

FETO is the Far East Theater of Operations. The memo notes that Sp1/c Newton Jones had just returned from the Far East where he'd been training native OSS units, and earlier had spent "several months in London" developing the booklet Personal Disguise and instructing groups in the European Theater. "War Paint" was clearly not an idle proposal — it had a program name, a training pipeline, and a chain of command (Colonel Peers had submitted something, the page cuts off mid-sentence).

Did it work? Declassified OSS materials and Detachment 101 histories (the famous Burma operation) confirm that white officers operating alongside Kachin guerrillas faced a brutal visibility problem in jungle terrain — a six-foot pale soldier next to local fighters was, as the memo dryly notes, "an outstanding target." Period accounts mention walnut-stain washes, potassium permanganate, and commercial dyes being used in the field. The British SOE ran parallel experiments; their agents inserted into Asia used similar staining techniques, sometimes supplemented by hair dye and dental modifications.

The dermatological reality was less glamorous than the program name. Skin stains streaked in tropical humidity, washed off in river crossings, and pooled unnaturally in skin creases. Multiple postwar debriefs noted that the disguise worked at a distance — exactly the distance that mattered for a sniper — but failed any close inspection.

The modern echo: "War Paint" is the direct ancestor of the camouflage face paints still issued to Special Forces today, and the technique resurfaced controversially in the CIA's later disguise programs run by Antonio Mendez (of Argo fame), who pioneered far more sophisticated prosthetics and complexion masks for operatives in the 1970s and 80s. The 1945 memo is essentially the prototype document: a small group of Field Photographic Branch officers — photographers, of all people — quietly inventing the tradecraft of looking like someone else.

It's also a reminder that "blending in" was once a literal chemistry problem solved with stain bottles, not a metaphor about cover stories.
