Is there a free PDF reader for Android that allows you to change the font and background color? I tried various ones and either they don't support the feature or it doesn't work. I would like a black background with red font, the ones that support night mode have white font which still burns my eyes after a while (red is much easier on the eyes being that it's the lowest energy level). I tried various screen adjuster apps but in addition to changing the white they also change the black and make it red creating more brightness. I tried saving the PDF as a text file and putting it on the tablet but the formatting cuts off sentences, omits words and makes it unreadable. I tried converting it to EPub and HTML with Calibre (a free converter) but over half an hour later it was still at one percent. The PDF file is quite big (over 150 MB), perhaps too big to really upload to a server to convert (well, I haven't tried yet, I may try that later but would prefer a PDF reader). Can someone help me?
