I would like to change the color (bg and fg) of the remark environment in a Beamer document. I have setup my document using:


I read in some other question that I should use something like:

\setbeamercolor{theorem text}{fg=black}

or something like

\setbeamercolor{block title example}{bg=orange,fg=white}

I have tried both, using remark or rem instead of theorem or example to no avail. I have to make it clear that I don't want to create a new environment, as I use Lyx and I need to stick to the default "remark" environment, only modified through the preamble.


I have checked that Lyx adds the following definitions to the preamble:


Is this a Lyx related question instead of a Beamer one?

Unfortunately no, as a new environment is defined to make the changes. As I want to use Lyx, this is precisely the kind of solutions that I cannot apply. – jcredberry Mar 27 '14 at 18:15
There's no remark environment predefined in beamer. – Gonzalo Medina Mar 27 '14 at 19:08
Thanks Gonzalo. Check on the UPDATE added to the question. – jcredberry Mar 27 '14 at 20:17
