Greenskin. The Green Goliath. The Jade Giant. The Incredible Hulk has had a variety of nicknames over the years, but one thing has always come through in his various monikers: the Hulk is green. Most people, in fact, think he’s always been green. Ask the average person on the street what they know about the Hulk and “he’s green” will probably come up, along with "get out of my face, nerd, I'm just trying to go to work."
The color has been synonymous with the character pretty much since Hulk’s inception in 1962, and it's really one of Ol’ Jade Jaws’s most defining characteristics. But as any comic fan worth their poly-bagged, unopened copy of Superman v2 #75 knows, it hasn’t always been that way.
One of the most powerful comic book characters ever, the Hulk has seen a multitude of changes since he was first conceived by Stan Lee and Jack Kirby, and some of those changes have been in coloring. You'd be hard-pressed to find someone who knows every color the Hulk has been; there are a few that only the most devoted comic book historians would know. Prepare to join those hallowed ranks and learn every color the Hulk has been over the course of comics history.
