East Germany kits Euro 1988 Qualifying

DDR team dressed his classical colors during qualification stage for the Euro 1988. At least for the games vs France (1986) and Iceland (1987) the white shirt logo shows in the middle of the chest,I found some pictures of the original shirt and logo is as shown here. If you look into the home and away colors for this team, normally you'll find that the blue shirt is home, but in 1987 and 1988 East Germans played with the white shirt as home. Can somebody tell us more about this?
