There is a six-part British documentary series called "World War I in Colour".
It was originally screened in 2003 on Channel 5 (it's one of the few good things that Channel 5 has shown) and is narrated by the actor Kenneth Branagh.
Its stars are the British WWI veterans Arthur Barraclough, Harry Patch and Arthur Halestrap, all of whom have since died. The veterans are interviewed in each of the six episodes and tell us of their horrific experiences during that war.
Virtually all of each episode - except some of the bits in which the veterans are interviewed when you see them instead - have film footage of WWI which has been colourised. Apart from the old fashioned uniforms and weapons the soldiers are using, you would be excused for thinking the footage was shot recently.
The six episodes are available on DVD.
