As Europe struggles with the historic influx of migrants and refugees in recent years, comparisons have been made with World War II when more than 60 million Europeans were forced to leave their homes as they fled persecution.

The images we have seen of Syrian, Iraqi and Afghan refugees, among many others nationalities, walking from Greece to Serbia, Croatia, Hungary and Germany are reminiscent of the searing photographs of refugees made during and after World War II.

TIME commissioned freelance photo editor Sanna Dullaway to colorize some of these iconic images.

Sanna Dullaway is a photo editor based in Sweden and the host of a monthly column on TIME LightBox on colorized photography. See more of her work here.
