\title{The \texttt{chalkboard} Beamer color theme}

\maketitle
\section{Overview}
Chalkboard is a Beamer color theme with a dark green background, warm
 off-white text, and yellow, blue, and pink accents. It is distributed as
\texttt{beamercolorthemechalkboard.sty}; the user-facing theme name is
\texttt{chalkboard}. The CTAN package name is
\texttt{beamercolortheme-chalkboard}. It requires Beamer and no extra
fonts or image assets.
\section{Installation and use}
For a single presentation, copy the style file into the directory containing
your main source. On Overleaf, upload it beside the main source. For a local
installation shared between projects, use the directory
\texttt{tex/latex/beamercolortheme-chalkboard/} under your personal TeX tree;
find that tree with \texttt{kpsewhich -var-value=TEXMFHOME}.

Load the main theme first and the color theme afterwards:
\begin{verbatim}
\documentclass{beamer}
\usetheme{Madrid}
\usecolortheme{chalkboard}
\begin{document}
\begin{frame}{Hello}
  Normal text and \alert{an important detail}.
\end{frame}
\end{document}
\end{verbatim}
No package options are defined. See \texttt{chalkboard-example.tex} and its
PDF for a title page, lists, mathematics, three block types, and the palette.
Compile either documentation or example source twice with pdfLaTeX from
the package directory.

\section{Palette and behavior}
\begin{center}
\begin{tabular}{lll}
\toprule
Color name & HTML value & Main use\\
\midrule
\texttt{chalkboard} & \texttt{2A3B33} & Background\\
\texttt{chalkboarddark} & \texttt{1F2B25} & Titles and palettes\\
\texttt{chalkboardlight} & \texttt{34483E} & Block bodies\\
\texttt{chalkwhite} & \texttt{E6E4D8} & Normal text\\
\texttt{chalkyellow} & \texttt{EBD58A} & Structure and standard titles\\
\texttt{chalkblue} & \texttt{9FC5E0} & Example text and titles\\
\texttt{chalkpink} & \texttt{F0A6A0} & Alerts and alert titles\\
\bottomrule
\end{tabular}
\end{center}
The theme sets normal text and background colors, the four palettes,
title and frame-title colors, author/date colors in headers and footers,
and standard, alert, and example block colors. Projected item labels use
dark green on yellow and a bold font.

In addition to colors, the theme selects rounded blocks without shadows
and the default rounded title page without shadows. It does not select
ball-shaped list markers: these depend on the main or inner theme. To
change these choices, apply your template or font settings after loading
Chalkboard. For example:
\begin{verbatim}
\setbeamertemplate{blocks}[default]
\setbeamerfont{item projected}{series=\mdseries}
\end{verbatim}
\section{Compatibility and customization}
Madrid is the reference combination. The default Beamer theme is also
supported; other themes can supply templates or later settings that affect
the result. The named colors above are available for use in your content.
Use Beamer's \verb|\setbeamercolor| after loading the theme to customize
individual elements.

Handout mode retains the dark background. There is no light/print mode.
Check the result on your presentation equipment: projector brightness and
room lighting can affect readability.
