"Reading", as the old Public Service Campaign used to say, "is fundamental!" 
It occurred to me to read the article a little more closely! 
The author says that hot rolls cool to that dark blue gray color and then start collecting a patina of rust. I'm guessing the shiny silver rolls are stainless.
Makes sense to me!
