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. This be­haviour can be op­tion­ally dis­abled, with the pro­vided colours also avail­able as “OwlRed”, “OwlGreen”, etc.
