Why does AC Milan always wear a white away jersey in the Champions League final?

Because AC Milan was assigned to the lower half, that is, the visiting team area, in the 2005 and 2007 Champions League 1/4 finals, Liverpool was the home team and AC Milan was the visiting team, so in the 2005 and 2007 Champions League finals, Liverpool should wear the home team's jersey, which is red, and Milan's home team's jersey is similar to Liverpool's color.
