+% \subsection{\themename color theme}
+%

+%
+% \subsubsection{Package dependencies}
+% \begin{macrocode}
+\RequirePackage{pgfopts}
+% \end{macrocode}
+%
+%
+%
+% \subsubsection{Options}
+%
+% \begin{macro}{headingcolor}
+% Select the color to use for all headings (title, section, frame, etc.).
+% \begin{macrocode}
+\def\headcol{black}
+\pgfkeys{
+ /trigon/color/headingcolor/.cd,

+}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{block}
+% Optionally removes the light grey background to block environments like
+% |theorem| and |example|.
+% \begin{macrocode}
+\pgfkeys{
+ /trigon/color/block/.cd,
+ .is choice,
+ transparent/.code=\trigon@block@transparent,
+ fill/.code=\trigon@block@fill
+}
+%

+%
+% \subsubsection{Base colors}
+%
+% \begin{macrocode}

+\definecolor{tSec}{HTML}{5FA4B0} % Green-Blue light
+\definecolor{tAccent}{HTML}{F07F3C} % Orange
+\definecolor{tGrey}{HTML}{E6E6E1} % Grey-Beige
+% \end{macrocode}
+%
+% \subsubsection{Derived elements}
+%
+% All the elements are set using the base colors defined here above.

+% \end{macrocode}
+%
+%
+% Block environments such as |theorem| and |example| have a |tGrey| background

+% \end{macrocode}
+% \end{macro}
+%
+% We first define hooks to change the case format of the titles.
+%
+% \begin{macrocode}
+\def\trigon@titleformat#1{#1}
+\def\trigon@subtitleformat#1{#1}
+\def\trigon@sectiontitleformat#1{#1}
+\def\trigon@frametitleformat#1{#1}
+% \end{macrocode}
+%
+% To make the uppercase and lowercase macros work in the title, subtitle, etc.,
+% we have to patch the appropriate |beamer| commands that set their values.
+% This solution was suggested by Enrico Gregorio in an answer to
+% \href{http://tex.stackexchange.com/questions/112526/}{this StackExchange
+% question}.

+% First of all, we define a few commands in order easily create the triangles
+% used as the main design elements of the theme. All these are defined with
+% respect to the |\paperwidth| and |\paperheight| of the document, so that it
+% fits the different aspect ratio possible.
+%
+% \begin{macro}{\leftTriangle}
+% Defines a triangle with the base on the left side (pointing right).
+% \begin{macrocode}
+\newcommand{\leftTriangle}[2]{
+ (#1,#2)
+ -- (0,{#2 + tan(30)*#1} )
+ -- (0,{#2 - tan(30)*#1} )

+% \begin{macro}{\righTriangle}
+% Defines a triangle with the base on the right side (pointing left).
+% \begin{macrocode}

+ -- (\the\paperwidth,{#2 - tan(30)*(\the\paperwidth-#1)} )
+ -- cycle;
+}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\topTriangle}
+% Defines a triangle with the base on the bottom side (pointing top).
+% \begin{macrocode}
+\newcommand{\topTriangle}[2]{

+ -- ({#1 - tan(60)*#2},0)
+ -- ({#1 + tan(60)*#2},0)
+ -- cycle;
+}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\leftColorTriangle}
+% Defines a colored triangle with the base on the left side (pointing right).
+% \begin{macrocode}
+\newcommand{\leftColorTriangle}[3]{

+%% ------------------------------------
+\section{Introduction}
+
+\themename found its origin and inspiration in the graphical guidelines
+resulting from the visual identity overhaul of the
+\href{https://www.uliege.be}{Univeristy of Liège} (Belgium).\\
+Although directly inspired from these guidelines, \themename was stripped out of
+any mention or specificities related the University and its faculties. This
+makes the \themename theme perfectly suitable for many different contexts.
+
+The final product provides a modern, elegant and versatile theme with a
+high degree of customization.
+
+\themename's codebase lives on
+\href{https://gitlab.com/thlamb/beamertheme-trigon} {Gitlab}. The implementation
+of this theme is strongly inspired from the excellent
+\href{https://github.com/matze/mtheme}{\textsc{Metropolis}} theme by Matthias
+Vogelgesang, from which it borrows numerous options.\newline
+Any feature request, issue report or merge requests are welcome.
+
+
+%% ------------------------------------
+\section{Getting Started}
+
+\subsection{Installing from Gitlab}
+
+If you want to use the cutting-edge development version of \themename, you can
+install it manually by following these steps:
+\begin{description}
+ \item[Download the source] from
+ \href{https://gitlab.com/thlamb/beamertheme-trigon}{\themename repository}
+ using |git clone| or as a \href{https://gitlab.com/thlamb/beamertheme-trigon/-/archive/master/beamertheme-trigon-master.zip}{zip archive} of the latest development version.
+ \item[Compile the style files] by running |make sty| inside the downloaded
+ directory. (Or run \LaTeX{} directly on |source/trigontheme.ins|.)
+ \item[Move the resulting |*.sty| files] to the folder containing your
+ presentation. To use \themename with many presentations, run
+ |make install| or move the |*.sty| files to a folder in your \TeX{} path
+ instead.
+ \item[Use the theme] by declaring |\usetheme{trigon}| in the preamble of your
+ document.
+\end{description}
+
+\themename uses the Make build system to offer the following installation
+options for advanced users:
+
+\begin{description}
+ \item[|make sty|] builds the theme style files.
+ \item[|make doc|] builds this documentation manual.
+ \item[|make demo|] builds a demo presentation to test the features of
+ \themename.
+ \item[|make all|] builds the theme and manual.
+ \item[|make clean|] removes the files generated by |make all|.
+ \item[|make install|] installs the theme into your local texmf folder.
+ \item[|make uninstall|] removes the theme from your local texmf folder.
+\end{description}
+
+
+\subsection{Other install methods}
+
+\themename will be proposed for integration on \href{https://www.ctan.org}{CTAN}
+shortly. It will then hopefully be integrated to texlive, miktex, etc. In the
+meantime, only the installation from Gitlab is possible.
+
+Once accepted on CTAN, the theme will also be made available on
+\href{https://www.overleaf.com}{Overleaf}.
+
+\subsection{A Minimal Example}
+
+The following code shows a minimal example of a Beamer presentation using
+\themename.
+
+\begin{lstlisting}
+\documentclass{beamer}
+\usetheme{trigon} % Use trigon theme
+\title{A minimal example}
+\subtitle{A subtitle example}
+\date{\today}
+\author{Thomas Lambert}
+\institute{Your university or company}
+\begin{document}
+ \maketitle
+ \section{First Section}
+ \begin{frame}{First Frame}
+ Hello, world!
+ \end{frame}
+\end{document}
+\end{lstlisting}
+
+
+\subsection{Dependencies}
+
+\themename depends on the |beamer| class and the following standard packages:
+\begin{itemize}
+ \item |tikz|
+ \item |pgfopts|
+\end{itemize}
+
+The theme works best with the open source
+\href{https://fonts.adobe.com/fonts/source-sans}{Source Sans Pro} font from
+Adobe.\newline
+Therefore, the package |sourcesanspro| is loaded by default with the theme.
+However, if the user prefers to select an other font, the theme option
+|nosourcefonts| can be used to prevent the font package from being loaded.
+
+
+%% ------------------------------------
+\section{Customization}
+
+\subsection{Package options}
+
+\themename provides a number of options, which can be set using a key=value
+interface. The primary way to set options is to provide a comma-separated list
+of option-value pairs when loading \themename in the preamble:
+\begin{lstlisting}
+\usetheme[option1=value1, option2=value2, ...]{trigon}
+\end{lstlisting}
+
+
+Options can be changed at any time --- even mid-presentation! --- with the
+|\trigonset| macro.
+\begin{lstlisting}
+\trigonset{option1=newvalue1, option2=newvalue2, ...}
+\end{lstlisting}
+
+The list of options is structured as shown in the following example.
+
+\DescribeOption{option key}{list of possible values}{default}{
+ A short description of the option.
+}
+
+As \themename implementation is heavily inspired from the excellent
+\href{https://github.com/matze/mtheme}{\textsc{Metropolis}} theme by Matthias
+Vogelgesang, many of \textsc{Metropolis} options are also available in
+\themename.
+
+\subsubsection{Main theme}
+
+\DescribeOption{titleformat}%
+ {regular, smallcaps, allsmallcaps, allcaps}
+ {regular}{
+ Changes the format of titles, subtitles, section titles, frame titles, and
+ the text on ``standout'' frames. The available options produce
+ Regular, \textsc{SmallCaps}, \textsc{\MakeLowercase{AllSmallCaps}}, or
+ \MakeUppercase{AllCaps} titles. Please refer to
+ Section~\ref{sec:titleformats} for known issues with these options.
+}
+
+\DescribeOption{usesourcefonts}{true,false}{true}{%
+ Choses if the |sourcesanspro| font package should be loaded |true| or not
+ |false|.

+ frame titles (see |titleformat|, above).
+}
+
+
+\subsection{Color Customization}
+
+The included \themename color theme is used by default, but its colors can be
+easily changed to suit your tastes. All of the theme's styles are defined in
+terms of four colors:
+\begin{itemize}
+ \item |tPrim| The primary theme color, used for main triangle elements, and
+ for headings and text if the appropriate options are selected.
+ \item |tSec| The secondary theme color (lighter shade of the primary color),
+ used for some triangle elements and example text.
+ \item |tAccent| The accent color, used mostly for alerted text.
+ \item |tGrey| A grey color, used for background elements (triangles, blocks,
+ etc.).
+\end{itemize}
+
+An easy way to customize the theme is to redefine these colors using
+
+\begin{lstlisting}
+ \colorlet{tPrim}{ ... }
+ \colorlet{tSec}{ ... }
+ \colorlet{tAccent}{ ... }
+ \colorlet{tGrey}{ ... }
+\end{lstlisting}
+in your preamble.
+
+\section{Tips \& Tricks}
+
+\subsection{Backup Slides}
+
+Speakers will often include extra slides at the end of their presentation to
+refer to during audience questions. One easy way to do this is to include the
+\verb|appendixnumberbeamer| package in your preamble and call \verb|\appendix|
+before your backup slides.
+
+\themename will automatically turn off slide numbering for slides in the
+appendix.
+
+
+\section{Known Issues}
+
+\subsection{Title formats}
+\label{sec:titleformats}
+
+Be aware that not every font supports small caps, so the |smallcaps| or
+|allsmallcaps| options may not work if you use a font other than
+|sourcesanspro|.
+
+The title format options |allsmallcaps| and |allcaps| are quite nice from an
+aesthetic point of view, but their use of |\MakeLowercase| and
+|\MakeUppercase| can cause unexpected problems. For example:
+
+\begin{itemize}
+ \item Some commands, like |\\|, do not work inside |\MakeLowercase| and
+ |\MakeUppercase|. (See \textsc{Metropolis}
+ \href{https://github.com/matze/mtheme/issues/125} {\#125})
+ \item Only alphabetic characters are affected by |\MakeLowercase|, so
+ numerals and punctuation remain at full height. This can spoil some of the
+ aesthetic benefits of |allsmallcaps|. (See \textsc{Metropolis}
+ \href{https://github.com/matze/mtheme/issues/33}{\#33})
+ \item |\MakeLowercase| and |\MakeUppercase| apply to math mode and
+ |\scshape| does not. This can easily introduce mathematical errors that
+ are hard to catch.
+ \item It is impossible to typeset symbols which are encoded as uppercase
+ letters in a different font. In particular, |\mathbb| and |\mathcal|
+ letters will be replaced by other math glyphs. (See \textsc{Metropolis}
+ \href{https://github.com/matze/mtheme/issues/153}{\#153})
+\end{itemize}
+
+The |allsmallcaps| and |allcaps| options are safe to use if your titles contain
+only alphabetic characters and do not require the expansion of any macros.
