Hi guys,
I just want to say how much I appreciate the effort you both have put into this. With memories fading and only relatively scant resources to draw upon, this period has become alive again for some of us. At this point, I don't think it's possible to have a definitive definition of color, so perhaps a few different sets could be done.
I have fond memories of my grandfather, who was in the first tanks to operate on the battlefield at Cambrai. His vehicle ran into mechanical troubles, and stalled over enemy lines. He was taken prisoner, and spent the rest of the war as a POW. He told me stories about the food, mainly a soup consisting of "greasy water with carrots ". He never ate carrots again after he got back.
S!
