Therefore, today we are going to see an interesting function of Adobe Reader that will allow us to change the color scheme of a PDF document so that the screen is not so bright, allowing a more comfortable and pleasant reading.

Invert the colors of a PDF to read better at night

Adobe Acrobat Reader is one of the most popular PDF viewers out there today. This program has a very neat interface and it will allow us to open any PDF document, read it, as well as make annotations within the text itself. It also allows us to fill in forms, use its magnifying glass to enlarge the text and select text and images from a document to discard or copy it. In addition, it has a digital signature validation system. And best of all, it is completely free and we can download it from this link .

Among the functions of this program, Adobe has provided it with a special configuration that includes the possibility of inverting the colors of any PDF document .

To activate this function we open the PDF file with Adobe Acrobat Reader. Once in its main menu we must click on the “Edition” tab, so that a list appears. At the bottom, click on the “Preferences” option.

Next, a new dialog window will appear. In it, we will click on the “Accessibility” option that we will find on the left, within the “Categories” section. This will show us in the right panel a series of options for the configuration of the document colors . Above all we must mark the option “Replace document colors”. Then we can choose between two options to mark

Flag Use High Contrast Colors

This will cause a drop-down panel to be enabled with different combinations, from which we can select the one that best suits us among “green text on black”, “yellow text on black”, “white text on black” and “black text on white. ».

To finish, click on “Accept” and we will check how the document’s color scheme changes automatically. Of course, we must bear in mind that the colors contained in the text may not be correct. If this is the case, we can choose to choose another of the different color combinations, until we find the one that best shows the document.

Use a custom color

In the event that the option of high contract colors does not satisfy us, we can choose the next option, “Custom Color”. Here we must click on the “Page background” and “Document text” check boxes, where we must choose our preferred colors and combine them to find the best option. Once chosen, click on “OK”, so that the color scheme of the document changes automatically.

These changes will not only affect the document that we have open, but will also affect all the documents that we open with Adobe Reader. This will cause that with each new document we have to repeat the process again to check which one best suits each situation.
