On first of november, almost an hour before sunrise.
Dawn just had begun, and in the blue light of the early morning the yellow leaves have a strange, somehow faded appearence - but nevertheless the colours have a saturated look.
I admit I would have preferred some clouds in the sky reflecting red light from a sun still behind the horizon, preferably with fog patches over the fields, but no such luck. Still, it was a nice morning, with slight frost in Lobau (whereas at my flat in Vienna proper there wasn't any frost).
