After the production of their second album, the Wiggles, who were called by their first names when they performed, began to wear costumes on stage as Fabinyi suggested and as the Cockroaches had done, and adopted colour-coded shirts: Greg in yellow, Murray in red, Jeff in purple, and Anthony in blue. The coloured shirts also made it easier for their young audience to identify them. As Field reported, the decision to emphasise colour was "a no-brainer, considering our pre-school-age audience". Cook (red) and Fatt (purple) already owned shirts in their colours, but Field (blue) and Page (yellow) "met in a Sydney department store and literally raced to see who got the blue shirt".
