Other forms: duskily; duskier; duskiest
Something that's dusky is dark or poorly lit, like the dusky walk home from your friend's house at twilight.
You can also use this adjective to describe a darker shade of a particular color, like your grandpa's favorite dusky pink roses or the dusky blue of the sky over the ocean just before a storm. Dusky and dusk, or the time just after the sun sets in the evening, come from the Middle English dosc, "obscure, tending to darkness, or shadowy."
