The song was inspired by Susan Lee, a character played by actress Emily Corrie in the TV series As If, who wore coloured dreadlocks.
Simon Amstell recorded an interview and footage behind the scenes for Channel 4 music show, Popworld.
The video begins by introducing the band members in a comical style, by getting Danny and Dougie's names wrong.
It also features the band messing around at various different scenes, but telling the overall main story about a girl with 5 colours in her hair, who was miserable and living in a black and white world.
The song was included on the "Please, Please" single release in the UK, as well as on the All the Greatest Hits deluxe fan edition.
