How to change the colour of a PDF's background?

[Mr__Magic_Man]

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.

Use this:

Tools > Edit PDF > More > Background > Add...

It's hard to recolour a rectangle because Acrobat isn't a graphics editor, no matter how people want it to be. Change the original, remake the PDF: anything else is a desperate last resort. Planned PDF editing is setting up to fail.
