+Also accepted are styles of the form `rgb#RrGgBb` and `onRgb#RrGgBb`, where `Rr`
+`Gg` and `Bb` are hexadecimal bytes (e.g. `rgb#f08000` for an orange foreground,
+and `onRgb#101060` for a deep purple background).  Naturally, your terminal
+needs to support 24-bit RGB for this to work.  When creating portable
+presentations, it might be better to stick with the named colours listed above.
