Terminology Problem? I Copied an Image From a PDF - Cannot Insert Color Text in PSE

I have a PDF file of a map open in Acrobat 8 Professional. I would like to annotate a snapshot from it using colored text in PSE6. I believe I've seen that layers in PSE6 can be "B/W or RGB." The layer in PSE6 seems to be B/W although I can't see how to confirm this. I can see my way to a 'kluge' by physically creating a printed copy of the map and then scanning it to a color jpg. This seems a very 'lossy' and time consuming way to overcome a problem that I might be able to solve using the Adobe software if I knew what words to use in a browser search to find the answer.

What am I missing?

thanks,
