Note that the bulk of these are from the home front, or at least well behind the front lines. There is a reason. Colour film (the correct spelling as this is in the UK) was lower resolution than black and white. The depiction of colour was also not accurate enough to trust for intelligence purposes. So a photographer going anywhere with potential intelligence value would have carried and used black and white film. Colour film, as we see in the OP images, was for glamor shots. The photographers documenting the realities of war as it happened shot black and white.

Does anyone really think those women used lipstick like that while running a lathe? Makeup like that was saved tucked away in secret boxes for the day that the photographer came around.
