+//! Output color themes: named palettes applied to help, tables, the
+//! version output and the completion menu.
+//!
+//! A theme is a set of SGR (Select Graphic Rendition) parameter strings
+//! (e.g. "1;38;5;75" = bold + 256-color 75). Painting wraps the text in
+//! "\x1b[<sgr>m...\x1b[0m". The "mono" theme uses empty sequences and is
+//! therefore plain text.
+
+/// One color theme.
