Adobe created the portable document format, or PDF, so that files could be shared easily across computer platforms. Adobe PDF documents can be multi-page documents or single-page documents, and can include an array of graphics and text in an assortment of colors. For people with vision problems, reading lighter-colored fonts can be difficult. You can change the preferences in Adobe Reader to show text in different colors.
