The idea is to encourage fans to brighten up Valley Parade by bringing along their own flags, which will be draped over the balcony and hung on museum walls.
If you have a flag which you would like to display, take it along to the museum by 1.15pm.
Flags will be taken down around 2.30pm and can be taken into the ground or collected later.
Flags taken into the stadium must be certified as fireproof to the appropriate British standard.
