Unique moment in the Premier League! A judge has forgotten the cards in the locker room!

The match between Birmingham and Everton, 1-1, counting for XXVIII phase of the Premier League had a unique moment, extremely rare in a game at this level.

The central of the game, Peter Walton, wanted to show the yellow card to Birmingham's midfielder, Jordon Mutch, but realized that he forgot the  cards in the locker room. He decided that an invisiblen card will have the same result as a real one.

But what would have happened  if the player concerned would have thought that it is a "red-invisible" and not an "yellow invisible"?
