I want to color some paragraphs that contain formulas, but I get an
error when filling out the PDF.
For example in the following example:

\begin_inset Formula \[ I=\pi \] \end_inset \end_layout \end_body
\end_document
I get the following error message:
Runaway argument? { \[ I=\int _{-\infty }^{\infty }\frac {1}{1+x^{2}}dx
\] ! Paragraph ended before \@textcolor was complete. <to be read again>
\par l.49 I suspect you've forgotten a `}', causing me to apply this
control sequence to too much text. How can we recover? My plan is to
forget the whole thing and hope for the best.
Suggestions?
Thank you
Stefano
