Hi, I've been searching a lot in the web for a solution for the colours in my pdf books not displaying correctly... they either appear oversaturated, darker, with blue, green or pinkish hue, or even as a negative image. I tried to open many different files (I have a lot of pdf ebooks) and all have the same problem Some say that is a problem with the program used to produce the dpf in the first place, and associated with the color scheme of windows vs mac... apple RGB and whatnot. I tried several apps (ibooks, goodreader, foxit, etc, etc) and they display just the same in every single app... ...except Adobe Reader, which displays it correctly, just like in windows or a mac (and very fast, so the problem is not rendering heavy files or hi-res pictures). So there must be a better explanation than that RGB thing... I though this was a problem with my specific iPad mini, until a friend bought one and I saw he had the same problem. So, can anyone explain why this is happening, and why only the adobe reader engine/renderer is working correctly? Anyway, for anyone with the same problem, this was the solution I found Have a nice day!
