World Cup Rugby

I have just turned on the Scotland v New Zealand match and am somewhat confused, both teams seem to be wearing the same coloured kit. New Zealand normally wear an all black kit, hence the name "All Blacks" and Scotland generally wear a dark blue kit. Today both teams are wearing black shorts and predominantly grey tops, the only differences appear to be that the All Blacks' kit has a little black on the shirt and the Scots have a little white. This is making watching the rugby rather confusing, except for the fact that the player scoring the try is playing for New Zealand!
