Pitch-dark

It was pitch-dark outside tonight.

There is nothing so deceptive as the distance of a light upon a pitch-dark night, and sometimes the glimmer seemed to be far away upon the horizon and sometimes it might have been within a few yards of us.

The night was pitch-dark. There wasn't the faintest star in the sky or a breath of wind. There was no babbling stream, there wasn't a single sound anywhere, and no smell of meadows or forest flowers.

It was pitch-dark in the cave.

The lamplight flickered one last time, and then it was pitch-dark.

It was pitch-dark.

The assassin crept into the royal bedchamber only after it was pitch-dark.
