As a rule, the home team is entitled to wear its first-choice playing attire. In order to clearly distinguish between the teams on the field of play, the UEFA administration may request that teams combine elements of their different approved playing attires. The UEFA administration issues a written decision regarding the playing attires in advance of each match.
If on the day of the match, in the opinion of the referee or the UEFA administration, the colours of the two teams could be confused, they will be changed. As a rule, in such cases it is the home team that has to change colours, for practical reasons. The decision taken by the UEFA administration in consultation with the referee is final.
