PDF is the universal document format that embeds fonts, layouts and images within the document without requiring special software to view the document. Adobe Reader allows you to open, view and make changes to PDF files and is available for free from the Adobe website. The accessibility feature of Adobe Reader allows you to change and replace font color. You can change the font color to any number of colors using this feature and then print the document with the changed color.
