In settings > configure okular > accessibility, there is an option to change light & dark colors. I set the light (background) color to black and the dark (text) color to light gray. The background is dark gray, and the text is light gray around the edges and black in the middle. After turning off text anti-aliasing, the text is black. http://i.imgur.com/F13sAf4.png http://i.imgur.com/1lNbGvG.png Reproducible: Always
