% \subsubsection{Base styles}
|
|
%
|
|
% All colors in \themename are derived from the definitions of |normal text|,
|
|
% |alerted text|, and |example text|.
|
|
%
|
|
% \begin{macrocode}
|
|
\newcommand{\metropolis@colors@dark}{
|
|
\setbeamercolor{normal text}{%

% \end{macrocode}

%

|
%
|
|
%
|
|
% \subsubsection{Derived colors}
|
|
%
|
|
% The titles and structural elements (e.g. |itemize| bullets) are set in the
|
|
% same color as |normal text|. This would ideally done by setting |normal text|
|
|
% as a parent style, which we do to set |titlelike|, but this doesn't work for
|
|
% |structure| as its foreground is set explicitly in
|
|
% |beamercolorthemedefault.sty|.
|
|
%
|
|
% \begin{macrocode}
|
|
\setbeamercolor{titlelike}{use=normal text, parent=normal text}
|
|
\setbeamercolor{author}{use=normal text, parent=normal text}
|
|
\setbeamercolor{date}{use=normal text, parent=normal text}
|
|
\setbeamercolor{institute}{use=normal text, parent=normal text}
|
|
\setbeamercolor{structure}{use=normal text, fg=normal text.fg}
|
|
% \end{macrocode}
|
|
%
|
|
% The “primary” palette should be used for the most important navigational
|
|
% elements, and possibly of other elements. \themename uses it for frame
|
|
% titles and slides.
|
|
%
|
|
% \begin{macrocode}
|
|
\setbeamercolor{palette primary}{%
|
|
use=normal text,
|
|
fg=normal text.bg,
|
|
bg=normal text.fg
|
|

|
}

% \end{macrocode}

|
%
|
|
% The \themename inner or outer themes optionally display progress
|
|
% bars in various locations. Their color is set by |progress bar| but the two
|
|
% different kinds can be customized separately. The horizontal rule on the
|
|
% title page is also set based on the progress bar color and can be customized
|
|
% with |title separator|.
|
|
%

% \begin{macrocode}

% Block environments such as |theorem| and |example| have no background color
|
|
% by default. The option |block=fill| sets a background color based on the

|
% background and foreground of |normal text|. The option |block=transparent|
|
|
% reverts the block environments to an empty background, which can be useful
|
|
% if changing colors mid-presentation.
