Inverting ebooks for better reading

I like ebooks. I don't like staring at lightbulbs. Hopefully, this one-liner will help others with the same problems I have with black-on-white text ebooks.

  1. Hello, thanks for the tip.

    Do you know that LCD screens use far less power when they are displaying full white ? For my part I reduce the luminocity a lot when I read ebooks on my LCD screen.

    Have nice Day

  2. Evince and Okular have options to read with inverted colors

  3. i quite like the compiz invert plugin for similar reasons.
