You should probably use the command \texorpdfstring{TEXstring}{PDFstring}See Hyperref-manualpdf p. 19 :hyperref takes the text for bookmarks from the arguments of commands like \section, which can contain things like math, colors, or font changes, none of which will display in bookmarks as is.
\texorpdfstring{TEXstring}{PDFstring}
For example,
\section{Pythagoras:
\texorpdfstring{$ a^2 + b^2 = c^2 $}{%
a\texttwosuperior\ + b\texttwosuperior\ =
c\texttwosuperior
}%
}
\section{\texorpdfstring{\textcolor{red}}{}{Red} Mars}
