Owl is a Beamer color theme for real-world conditions. Its dark and light themes and projector-optimized palette help you create slides you can count on to be readable in the presentation room.

Owl was designed with three guiding principles in mind:

Simple colours = no distractions

Owl uses black, white, and slight grey tones for the structural elements of each Beamer frame, putting the focus of each slide on your content.

Dark and bright rooms, dark and light themes

A white background is best for visibility in brightly-lit rooms, whereas a black one can be easier on the eyes in rooms with low ambient lighting. Owl provides both dark and light themes, easily configurable with the package options.

A palette optimized for common projectors

Business and university projectors are often calibrated with an extremely bright green channel and very dim red and blue channels. Owl redefines the basic colour names red, green, blue, yellow, violet, brown, orange, and cyan to attractive hues that are still visible on these projectors.

Owl is available on CTAN and comes bundled with the latest TeX Live distribution.
