   Under the Cloak — visual system

   The palette is metallurgical, and it carries meaning rather than decorating.
   Brass is a held key. Verdigris is what brass becomes once it is exposed —
   so it marks the values that are public on purpose. Rust is failure.
   Steel is structure. Nothing is coloured for flavour; if something is brass,
   it is because a person is holding it.
