how to export red colored TeX to latex

[Uwe Brauer]

Hi

I want to obtain a latex file that contains

\textcolor{red}{$\delta \phi = \frac{2 m}{R}$}


However when I add 
\textcolor{red}{$\delta \phi = \frac{2 m}{R}$}

To an org file and export it as Latex, the construct ends up like this


\textcolor{red}\{\(\delta \phi = \frac{2 m}{R}\)\}

Which is wrong.

Any ideas how to obtain the correctly exported expression?

Thanks
