I'm new to OSX and have a copy of OSX Yosemite.
I really like iBooks and Preview, but I need a night theme or the option to invert colors as in Linux with Gnome's Document Viewer.
I'm aware that I can globally invert colors through accessibility options, but my goal is to Alt+Tab a book and be able to write code. Global invert colors would mess up my text editor color scheme, terminal colors and many more.
So, does anyone know another way to achieve this inverted color effect for PDF viewing? I'm open to using a different PDF reader if it has the option to invert colors or any other method that allows me to invert colors only for Preview/iBooks.
