The Blues lifted Non-League's showpiece trophy twice in successive seasons in 2004 and 2005 while wearing their all sky blue kit and officials are urging supporters to colour code with them for the first qualifying round clash after announcing that they'd be wearing their lucky strip again.
In a message to fans on Facebook on Friday ahead of the 3pm kick-off in Essex, the club said: "We are asking fans to dig deep into their wardrobes, find them retro shirts and turn Mill Field into a sea of sky blue as we did to Villa Park and Upton Park."
