  \frametitle{Non-Brand Colors}
  The package \verb|ltx-talk| itself provides an \verb|\alert{}| command which uses \alert{this red} color by default.
  \vspace{1em}

  It also provides a named color called \verb|example| which is \textcolor{example}{green}.
  \vspace{1em}

  Additionally, \verb|tamu-talk| provides two off-brand colors that pair well with maroon:

  \bigskip
  \begin{sidebar}[forest]
    \textbf{forest} (off-brand).
  \end{sidebar}

  \bigskip
  \begin{sidebar}[slate]
    \textbf{slate} (off-brand).
  \end{sidebar}

  Use \verb|\appendix| to section off backup slides (to avoid running up the page counter).

  \bigskip
  % gobble=N strips the first N characters of leading whitespace from
  % every line of the Verbatim block. It lets this block be indented in
  % the .tex source (to read cleanly alongside the surrounding code)
  % without that indentation showing up in the typeset output.
