Change a window’s background colour in Preview on Mac
Preview shows a grey background behind PDFs and images. In a PDF or image, you see the background if you expand the window larger than the size of the document; in an image, you can also see the background through any transparent sections. You can change the background colour.
In the Preview app
on your Mac, choose Preview > Preferences, then click General.Click the “Window background” colour well, then choose a colour.
