dark, evening, dusk
昏 centers on the dimming of light at day's end: the darkness of evening and dusk.
昏 combines 氏 (a pictograph of a person bending down) with 日 (sun), suggesting the sun lowering as a person bends, representing dusk or darkness.
The sun 日 is setting below a person bending down 氏, bringing darkness and evening.
For コン, imagine a con man sneaking around at dusk: con -> コン, and the darkness hides his tricks.
