How to change a note background in the preview app from transparent to any other colour? When I add a note to a highlighted text (right click - Add Note), the background is transparent, which makes it difficult to read because it overlaps with the PDF text (example screenshot below). I know this does not happen when I add a note directly without linking it to a text. I could do it that way, but I prefer to have comments linked to a specific text I select. Does anybody know how to make the background not transparent? Thanks in advance.
First click the note, then press the button shown in the picture and select a color.
