Change Background Color via Properties Panel
Use the properties or format panel to modify the fill color of editable boxes, such as form fields and annotations.
This is the standard method for recoloring active elements in a PDF. Editable elements typically have dedicated appearance settings where stroke and fill colors can be modified.
Click on the box, form field, or annotation you wish to recolor to highlight it.
Right-click the selected box and choose 'Properties' from the context menu, or open the formatting pane in your PDF editor.
In the Properties dialog, click on the 'Appearance' or 'Style' tab.
Locate the 'Fill Color' or 'Background Color' option, select your desired color from the palette, and click 'OK' or close the panel to apply the changes.

Frequently Asked Questions
Why can't I select the box to change its color?
If the box cannot be selected, it is likely part of a flattened image or scanned page. You cannot change its color directly. Instead, you can draw a new colored shape over it using the commenting tools, or edit the original source document.
Will changing the background color hide the text inside the box?
It depends on how the PDF layers are arranged. If you are adding a new colored shape over existing text, the text will be hidden. To prevent this, adjust the opacity of the fill color, or ensure you are modifying the actual background property of the text box itself so the text remains visible.
Can I change the background color of an entire PDF page on Mac?
Yes. In comprehensive PDF editors like WPS Office, you can navigate to the 'Page' or 'Edit' tab, select 'Background', and apply a solid color or an image to the entire background of the document.
