It’s difficult to express the horrors perpetrated by the Nazi Party under Hitler’s command. This is a dark chapter of human history — the darkest of all — and must never be allowed to repeat itself. As a result, World War II has become a crucial part of education around the world. Those who have studied history, then, have surely encountered monochrome images of Hitler and perhaps seen black-and-white footage of his frenzied speeches.

His notorious visage remains engrained on humanity’s collective consciousness — like a stubborn stain that just refuses to be washed away. From his characteristic pencil mustache to his severely parted hair and hateful uniform, almost everybody is familiar with the failed Führer’s appearance. Color photographs of him, though, are exceedingly rare.

As HuffPost reports, color film was available to photographers before the war (it first became available in 1935-1936), but very few used it in an official capacity during the conflict. One who did was Hugo Jaeger, a photographer in Hitler’s employ. As a result, Jaeger had unique access to the Nazi leader’s life and took a great many official photographs. Although Jaeger feared retribution for his former role after the Axis powers’ defeat, he and his photographs survived the conflict and its aftermath.

Yeager’s archives and others’ colorization efforts both show us what the infamous historical figure looked like in color. His dark brown hair and mustache, pale skin, and rather cold eyes are unmistakable.
