More dusky; darker or more shadowy than something else; more dim or tending more toward twilight.
From 'dusky' (meaning 'somewhat dark' or 'twilight-colored') plus the comparative suffix '-er,' following standard English patterns for comparative adjectives.
In literature, 'duskier' often describes skin tones or landscapes—the word appears frequently in Romantic poetry to capture subtle gradations of darkness that a simple 'darker' wouldn't quite capture.
