Cannot get background color to export to pdf
I am trying to create a book cover which will have a background colour. There are several youtubes covering issues with creating a background color whcih I have been through and they all seem so simple, either create a layer or send to back etc. However, I am reduced to experimenting with one word on the document and adding a bckground layer, and whatever I do I cannot get the pdf to show anything other than a white background. Am I missing something obvious? The usual reposnse seem to be that people are using "paper" as the background but if you create a layer then go Window/Color/Color, that option does not appear.
