How to change the colour of a PDF's background?
I have a pdf that I've opened in Acrobat DC. I want to change the color of the background in one of the pages. The content sidebar tells me that this background is a "path" object.
If I try to edit the object in photoshop, photoshop gives me an error that says that "a colour was using an unsupported color space". If I delete the background and try to create a new one using the shape drawing tool in the comment toolbar, it covers the text and there is no option to "send to back" or anything similar. I don't know why it's so hard just to recolour a rectangle.
