The Germans had, and used, color film. Most of the photos in Signal were in black and white, but a few were in color. Here's a link to a few (scroll down to the color photos of the Afrika Korps). Of course, those are the desert uniforms, not the Feldgrau or SS. For those you would need to look through the print versions of the magazine.
