In this video, we will show users how to change the color of a PDF document's text and background for ease of reading and accessibility in PDF Studio, Qoppa Software's PDF reader and editor. The video will demonstrate how a user can pick a color combination from the presets provided, while also utilizing a couple other features to only edit black text and line art. Lastly, the video shows users how they can customize and create their own color combinations to help them see documents better if they have specific limitations such as a visual impairment or are in a dimly lit environment. Feature coming in PDF Studio 2021.
