Yeah, Dio was on Dehumanizer. It was chock full of great cuts such as TV Crimes, After All (The Dead), Master of Insanity, Time Machine, and I.
Ah, I could see that. I'm a huge Dio fanboy, so it tends to rank pretty highly for me, plus it has The Mob Rules, Sign of the Southern Cross, Falling Off The Edge of The World, Turn Up The Night, and Country Girl
Personally, I'd also put all of the Tony Martin albums, save for Forbidden, in green, but below all the Dio albums and a good chunk of Ozzy material.
