Oleg....I admit this is one of those detail posts...and i half appolgise for it...In the shot with the 109 having been shot down we have a really nice pic of a town...it looks great (here's the but) but 95% of the house have a clay red roof. we have a lot of Slate (very dark grey) roofed properties (particually pre 1940) in the UK. The only reason i bring it up is it may actually help break up the sea of brownish-red...sorry for my first...i'm going to be anal about detail post: it is meant with the best intentions.
edit: quick example:
