You can see that it's dark but not completely dark – there's some definite blue going on behind the banks of clouds. (And would be a lot more blue, if there weren't so many clouds...)
Orkney and Shetland have what they call "simmer dim" – those twilight summer nights that never get completely dark; the sun goes down, but the sky never moves beyond an extended twilight. But I wasn't expecting quite so much light in the sky at midnight down here in Aberdeen!
Today, on the solstice, sunrise was 4:12 am and sunset will be 10:08 pm. Contrasts rather wonderfully with the 3:26 pm sunset of the winter solstice! (Here's my post from then, half a year ago.)
