Thanks for the reply Oleg. You are right about colour, I wasn't focusing on that, but I was more intrigued by the use of trees. IMO, apart from in forest areas with larger trees, small trees/scrubs/bushes should be the most frequent on the map.
Excellent work.
I did have a website that I looked at once which had aerial shots of areas in England around the 1940's. I can't find the site though.
