World War I Photo Colorization/Restoration with Flux.1 Kontext [pro]

I’ve got some old photos from a family member that served on the Western front in World War I.
I used Flux.1 Kontext for colorization, using the prompt “Turn this into a color photograph”. Quite happy with the results, impressive that it largely keeps the faces intact.

Color of the clothing might not be period accurate, and some photos look more colorized than real color photos, but still pretty cool.
