England may have to wear red and occupy the away dressing room when they begin their Rugby World Cup campaign against Fiji at Twickenham on 18 September.
World Cup rules see countries assigned as either Team A or Team B for each fixture, via a random draw.
Team A is classed as the home side and given the pick of kit and changing room.
As Fiji's first kit is white, that could see Stuart Lancaster's men as the away side, despite being host nation.
England have to yet to confirm what their second-choice kit will be for the tournament, but it is expected to be red.
They wore red when they beat Samoa 28-9 at Twickenham last November.
After playing Fiji, England face Wales and Australia at Twickenham before a final Pool A fixture against qualifiers Uruguay at Manchester City's Etihad Stadium.
