to be added

- Cá Bảy Màu has a Melbourne accent.

- This story received an interlude, titled A Scene, in The Book of the Peace Dossier. The vignette's title has a hidden meaning in that the list of locations it gives (forest, grassland, sky) gives an order of book of A lines in What Keeps Their Lines Alive that unite into the "A scene", hinting at events after the end of the story.
- The story was accompanied in the author-curated Spotify playlist by the songs Clam, Crab, Cockle, Cowrie by Joanna Newsom, Then the Morning Comes by Smash Mouth, and Solitude Standing by Suzanne Vega. Then the Morning Comes was intended to be the "background track" for Cá Bảy Màu.
- The story was inspired by Bertolt Brecht's dialectical theater, particularly St Joan of the Stockyards; the title is a reference to the line "What keeps mankind alive?" in The Threepenny Opera.
