Very lightly so. I have a couple of Queen folders in D2 that've developed some light grey patina with handling & pocket carry. Nothing dramatic, as with a steel like 1095 or CV - but it's there.
I think most of the patina that shows up is dependent upon some handling or use. My other Queens in D2, that I've kept stashed away and not handled, don't show the same effect.
D2 isn't quite stainless, because there's not enough free chromium to make it so. A good bit of the chromium in D2 goes instead to carbides.
