By the time we reached the hilltop, the sky had duskened into a soft purple.

Every evening, the old lamp post duskens the corner of the park, casting long shadows.

The horizon was duskening slowly as the sun sank behind the hills.

The mist began to dusken the distant hills, making them barely visible.

The old lighthouse blinked duskly as the fog rolled in.

She arranged the dusky-blues on the palette before beginning the watercolor.

The dusky-blue perched briefly on the wattle blossom before fluttering away.

I watched a dusky warbler flit through the reeds at dawn, its thin call barely louder than the breeze.

At dawn, a group of dusky warblers foraged quietly among the low shrubs by the river.

A dusky tit flitted between the branches, its soft call barely audible over the rustling leaves.
