Preview: Adjust Color greyed out for PDFs

Just scanned a bunch of pages as a PDF and opened it in Preview. The levels were off so I wanted to Adjust Color, but it was greyed out. Am I correct in assuming that this only works with image files, not PDFs?

A PDF file cannot be edited like a document file except using Adobe Acrobat. You can edit the original document, then create a new PDF. This is also true of image files if they have already been made into PDFs.
