Gerard Way dyed his hair in an act of rebellion against being a rocker in his 30s.

The My Chemical Romance singer has coloured his locks bright Pink ahead of the release of his group's fourth album 'Danger Days: The True Lives of the Fabulous Killjoys', and admits his change of image was a deliberate move to save the group from being categorised with other older musicians.

He said: "I'm happier, but I think in some odd ways more rebellious.

"In some ways the colour is more rebellious, even if it's self-rebellion, there's no big, secret, hidden enemy.

"We're in our 30s and we're in a rock band and you see things start to happen with bands at that period of life. I think it was a rebellion against that, against being brought into that whole modern rock thing."

The 33-year-old star also admitted the group's introduction of more colour in their wardrobe away from the blacks which dominated their look around their last album 'The Black Parade' was a gradual move.

He explained: "Every week someone would show up with something new that was colour, like, 'Oh I got these sneakers that are in colour,' and it kind of crept in almost like a virus into our lives.

"And then we had normal-looking wardrobes after a while."

'Danger Days: The True Lives of the Fabulous Killjoys' is released on November 22.
