The Vimy Foundation in Toronto chose 150 black and white photos from archives across Canada and transformed them into colourful reflections of the events of a century ago. The photos have been published in a book ‘They Fought In Colour’ and will also be displayed at the Canadian War Museum in Ottawa until 3 January 2019.

Similar technology was used by filmmaker Sir Peter Jackson to revamp black and white archive footage of the First World War into a full-length colour film called ‘They Shall Grow Not Old’.

The stills showcase a wide variety of events from the conflict; some depict events strongly associated in the public imagination with the war - soldiers struggling through the mud, peering over the top of a trench and walking through the ruins of a French town. Others show more light-hearted events; soldiers ice-skating in the middle of winter, dressing up in drag for a concert and celebrating the Chinese New Year.

"A lot of those details - people's eyes and their expression and the backgrounds and the landscapes - are lost in black and white compared to colour," Jeremy Diamond, executive director of the Vimy Foundation, told the BBC. "It gives a great perspective of real events. They're suddenly the real faces of real people."

The Great War proved a seminal event in the history of Canada and Newfoundland – then a separate Dominion within the British Empire. At the time Canada had a population of eight million people, of whom 625,000 fought for King and Empire. Around 60,000 were killed and a further 173,000 were wounded.
