Hi,
I'm preparing slides with beamer that content tikzpicture and I remarke a strange problem: when I use the opacity option of tikz to plot a transparent circle in a tikzpicture, all colors of the theme change (it doesn't depend on the theme)
An ECM is the following: I take the exemple
/solutions/conference-talks/conference-ornate-20min.fr.tex
and I add the following frame:
\frame{
\frametitle{aaaaaaaa}
blabla
\begin{tikzpicture}
\path<1>[fill=red] (0,0) circle (2cm);
\path<2>[fill=red, fill opacity=0.1] (0,0) circle (2cm);
\end{tikzpicture}
\egroup
}
Do you have an idea how to constrain the action of opacity only to a path?
Thank you
Gloria
PS Sorry for my English, I hope that you understand.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Insert this code in you document:
\pdfpageattr {/Group << /S /Transparency /I true /CS /DeviceRGB>>}
This worked when I did a quick test. The colors were not shifted. However, I still notice a subtle change in how text is displayed in Adobe Acrobat 7.0.

Following martin_heller's link I found this interesting discussion:

In this post a possible workaround was given:
