How to Darken Light PDF Files

Do not get an impression that you cannot modify or adjust colour of PDF files. You can improvise the colour scheme of these files including shade of the colour itself. If a file is in a light shade, you can darken it as much as you want. The process is easier as compared with editing functions of some other files.

Just follow a few simple steps in Adobe’s setting and you can move the colour shading both ways, lighten or darken it.  This is not just the background colour of the file itself but colour of text and margins or styling if it is with the file.
