Despite the fact that in the Southern Ural it was sunny and hot all July and August, the weather occasionally presented surprises. Sometimes it was real thunderstorms, sometimes it was just dark clouds. The dark clouds that covered the whole sky. Like these ones.
And, it's not even evening yet. This is the middle of the day, about 5:00 p.m. It was very dark.
Black hour photography, not blue.
