Beamer color theme owl

The effectiveness of a colour scheme is heavily dependent on the conditions you present in. Colours that look nice on a computer screen may be invisible projected; colours that stand out in a lit room may strain the eyes in a dark room. If possible, you should carefully choose from Beamer's wide variety of colour themes to find one that fits your presentation's individual needs.

The above paragraph would be excellent advice, except for one thing — only a handful of pre-selected colour themes are publicly available for Beamer. The vast majority of Beamer presentations use one of the built-in colour themes, which are effective in some conditions but inadequate in others. The goal of this package is to reduce the number of situations you find yourself without any good colour options. owl is a flexible dark or light colour theme designed for maximum readability in environments where most themes fall flat.

Examples

The `owl` colour theme used with the Beamer themes `Hannover`, `Pittsburgh`, and `metropolis`

Installation

Installing owl, as with any other package, involves just three easy steps:

  1. Download the source as a zip archive or with a git clone of this Git repository.
  1. Compile beamercolorthemeowl.ins with to produce the package file beamercolorthemeowl.sty.
  1. Move the .sty file to the folder containing your presentation or a directory in your path.

That's it! We are working on a CTAN release which would make it even easier to install through your distribution's package manager.

Usage

Once you have downloaded and installed the beamercolorowl package, using it is a piece of cake:

\usecolortheme{owl}

Unlike many Beamer themes, owl defaults to a dark theme with white text on a black background. This is particularly recommended for presentations with low ambient lighting, where it has the most advantages.

If you expect to present in a brightly-lit room or with a weak projector, you may wish to use to use the snowy option to use black text on a white background:

\usecolortheme[snowy]{owl}

In addition to setting the colour scheme of your slides, owl redefines the redefines the basic colour names red, green, blue, yellow, violet, brown, orange, and cyan to hues that are more visible when when displayed by some projectors. If you do not want these colour names to be redefined, use the cautious option when loading owl:

 \usecolortheme[cautious]{owl}

In either case, owl-defined colours will be available as OwlRed, OwlGreen, and so forth.`OwlRed`, `OwlGreen`, `OwlBlue`, and `OwlYellow`

Contributions

The biggest way you can help owl is by sharing your experience using it. Our goal with owl is to provide colours that are as visible as possible, even in unfavourable presenting conditions, and that is very difficult to test with only one pair of eyes and a handful of projectors!

If you have used owl or seen it used, we would greatly appreciate your opinion on how it performed. Please open a GitHub Issue or privately email ross@rosschurchley.com with as much of the following information as you can:

  • The version of owl used.
  • The Beamer theme, if any, that was used together with owl.
  • Whether owl was used as a dark or light theme.
  • Details on the room (auditorium, large room, small room, ...)
  • Details on the lighting conditions (brightly lit, dark, windows, ...)
  • Details, if known, on the reporter's vision (glasses, colour deficiencies, ...)
  • Your opinion on:
    • whether normal text was visible against the background.
      • whether the provided colours (OwlRed, OwlBlue, etc) were legible against the background.
      • whether the provided colours (OwlRed, OwlBlue, etc) were distinguishable from each other and from the normal text colour.

We also welcome technical feedback and bug reports in the form of GitHub Issues and pull requests.

beamercolorthemeowl – A flexible beamer color theme to maximize visibility

This package provides a flexible dark or light colour theme designed for maximum readability in environments where most themes fall flat.

Main features:

  • Dark color theme for presenting in low-light conditions.
  • Optional light color theme for presenting in bright ambient light.
  • Redefines color names “red”, “green”, “blue”, “yellow” to values that are visible when displayed by certain projectors, particularly those with a very bright green channel and dim red and blue channels.
