beamercolortheme-chalkboard

Version 0.1.0 (2026-10-15; packaging revised 2026-10-16)

A chalkboard-inspired dark green color theme for Beamer, with warm off-white text and yellow, blue, and pink accents. It styles titles, palettes, blocks, and projected items, and disables shadows on blocks and the title page.

The CTAN package name is beamercolortheme-chalkboard. The runtime file is beamercolorthemechalkboard.sty, as required by Beamer's \usecolortheme{chalkboard} naming convention.

Quick start

Copy beamercolorthemechalkboard.sty beside your presentation and compile:

\documentclass{beamer}
\usetheme{Madrid}
\usecolortheme{chalkboard}
\begin{document}
\begin{frame}{Hello}
  Normal text, \alert{an alert}, and $E=mc^2$.
\end{frame}
\end{document}

Load the color theme after the main theme. No theme options are provided. Beamer is required; no extra fonts or external graphics are needed. The package uses the color facilities supplied by Beamer. For a persistent local installation, place the style file in TEXMFHOME/tex/latex/beamercolortheme-chalkboard/ (find TEXMFHOME with kpsewhich -var-value=TEXMFHOME). Overleaf users can upload the style file beside their main .tex file.

Documentation and example

Read beamercolortheme-chalkboard-doc.pdf and chalkboard-example.pdf. Build each PDF by running pdfLaTeX twice on its corresponding .tex file from this directory. The example uses Madrid; the theme also works with the default Beamer theme. Other themes may override particular settings.

This is primarily a color theme, but it also makes projected item labels bold, selects rounded blocks without shadows, and selects the default rounded title page without shadows. It does not select ball-shaped list markers; those are chosen by the main or inner theme. Load your own template or font customizations after the color theme to override these choices. Dark backgrounds also apply in handout mode; there is no light/print option. Test readability on the projector and in the lighting used for your talk.
