Jambro Beamer Theme

Ambrogio Cesa-Bianchi's theme for academic and policy-oriented Beamer presentations: a clean, minimalist layout with a subtle color palette, modern typography, and a spacious design. It adds TikZ-based annotation tools — sketched arrows and handwritten-style fonts — plus pencil-style highlighting, underlining, and boxing.

A fully worked feature showcase is in Demo.tex — see the rendered Demo.pdf.

Status: v1.3-dev. Backwards-compatible within the 1.x line; changes are recorded in ChangeLog.md.

Getting Started

Download beamerthemejambro.sty to the folder containing your presentation (or install it in your local TeX tree), then load it with \usetheme{jambro}:

\documentclass{beamer}
\usetheme{jambro}

The theme loads its own dependencies (fonts, TikZ, tcolorbox, tabularx, and the Augie handwriting font); a recent TeX Live (2022 or newer) is recommended. Features that draw arrows to named nodes need two compiler passes to resolve. Compile with latexmk -pdf Demo.tex.

Package options

Theme options are passed as class options to \documentclass[…]{beamer}:

Option	Effect
`red`	Red color scheme (default is blue).
`night`	Dark-mode color scheme (overrides `red`).
`light`	Fira Sans Light body font (default is Fira Sans Book).
`cabin`	Switch to the Cabin font family.
`roboto`	Switch to the Roboto font family.
`3to2`	3:2 aspect ratio (default is 16:9).
`itemsep`	Generous itemize spacing (default is standard Beamer spacing).
`onesec`	Show only the current section in the footline.
`centertitle`	Center frame titles.
`shownotes`	Display speaker notes alongside slides.
`handout2x1`	2×1 handout layout for printing.
`wiggle=<n>`	Amplitude (pt) of the pencil/sketch effect (default `0.4`; larger = more expressive).
`hidememo`	Suppress every `\memo{…}` for a clean final build.

Public API

Typography & fonts

Command	Usage
`\hand`	Switch to the Augie handwriting font; use inside a group: `{\hand …}`.
`\handbold[<stroke>]{text}`	Bold handwriting; optional stroke width (default `0.6`).

Pencil marks & arrows

Command	Usage
`\lapis[<color>]{text}`	Hand-drawn underline (default color `carandache` gold).
`\lapisbox[color=<c>,label=<id>]{text}`	Inline pencil box; `label=` names a TikZ node for arrow targeting.
`\lapisboxeq[color=<c>,label=<id>]{a=b}`	Pencil box around an equation.
`\jarrowu` `\jarrowd` `\jarrowl` `\jarrowr`	Inline sketched arrows (up/down/left/right). Options: `color=`, `len=`, `lw=`, `pad=`.
`\marker{name}{text}`	Wrap visible text in a named node; a later `tikzpicture[tpstyle]` draws an arrow to it.
`\lapisnote[<options>]{node}{text}`	One-step shortcut to attach a handwritten note to a named `node` via an arrow (options: `color=`, `xshift=`, `yshift=`, `from=`, `to=`, `bend=`, `width=`).
`\stabilo[<color>]{text}`	Highlighter-style marking (default yellow).

Notes & annotations

Command	Usage
`\NB[<width>]{text}`	Note call-out; optional width (default full width).
`\memo[user=<u>,color=<c>]{text}`	Draft annotation; defaults via `\memouser` / `\memocolor`; hidden by the `hidememo` option.
`\shownotesblock{text}`, `\shownotesblockzero{text}`	Speaker-notes blocks (shown in `shownotes` mode; `…zero` targets the title slide).

Math, tables & code

Command	Usage
`\EE[…]`	Expectation operator.
`Y` / `S` columns + `\tablesize`	Auto-width `tabularx` columns; `\tablesize` for compact table text.
`\sym{***}`	Significance stars (rendered, but kept machine-readable).
`\jverb{…}`, `jVerb` (env)	Inline / block verbatim.
`\jcode{…}`, `\jCode{…}`	Inline / multi-line code (non-verbatim).
`\citej{ref}`	Citation typeset in the theme's main color.
`\vs{<n>}`	`\vspace` shortcut in tenths of a cm.
`changemargin` (env)	Temporarily change the left/right margins.
`\cmark` / `\xmark`	Check / cross marks.

Colors

Defined centrally and reusable anywhere a color is accepted:

Base palette: main, title, text, note, light, tomato, cobalt, carandache / gold, green, purple, maroon, brick, mint, bubble.
Highlights: hlight, hlightYellow, hlightPurple (used by \stabilo).
BoE palette: BoEblue, BoEacqua, BoEorange, BoEpurple, BoEgold, BoEgray, BoEred.

The red and night options remap the base palette.

Manual and examples

A slide deck (Demo.pdf and the corresponding Demo.tex) provides more information on the features of the theme and a series of examples.
