Really depends on the colour scheme. But dark blue and gold, or black and gold can look dope in my opinion.

F.W. Murnau und Fritz Lang liegen weinend in ihren Gräbern.

Those are actually not the norm either. Well, depending on where exactly you are I suppose, but where I am from most forests are kinda diverse but not really.

There is almost no real forest left in Germany anyways. We just recently started to leave forest be forest again and it will take centuries or millennia for it to become a natural forest again. Which then would probably be much more resilient to climate change than what we have today.
