Allee's "Death" tries to describe dying by turning it into a color. Black becomes the thing the speaker can see, hear, smell, taste and feel, so each sense gets a line of its own. Black is a life slipping out of someone's eyes, the quiet of a last breath, the smell of something approaching, and the taste of rotting flesh. The images move from the almost gentle (a whisper) to the disgusting (decay), which makes death feel less peaceful the closer we get to it.
The speaker sounds hushed and unflinching rather than panicked. There's no comfort offered, no mention of an afterlife, just a plain list of what death seems like. The final line stands apart from the rest and shifts from the senses to a feeling: "the end of it all." It's blunt and a little hopeless. The mood is cold, heavy and bleak, and the short, repeated "Black" openings make it feel like a slow, steady countdown.
