Appendices

• To create an appendix:
  \appendix 
  \section*{Appendix: Color Figures}  % use *-form to suppress numbering
• To number appendix figures (or equations, etc.) differently from the main body:
  \renewcommand{\thefigure}{A-\arabic{figure}} % redefine the command that creates the figure number; the new numbering scheme is now A-1, A-2, ...
  \setcounter{figure}{0}  % reset counter
