A lot of WWII film- especially stuff from the Germans in North Africa and the early Russian campaign, and the American campaign in the Pacific Theatre- was actually filmed in colour. There’s a wee bit of stuff from the British in colour too, FWIW.

Thanks for the quick replys, the link to PBS was very helpfull.
