http://en.wikipedia.org/wiki/Penalty_card It appears that the red card and the yellow card are British inventions and were invented so as to assist communication through the language barrier between a referee and a player at an international football match where the referee and the player may perhaps not speak the same language. My opinion is that it would be a good to encode the cards with variation selector capability such that an author may request monochrome heraldic hatching style or coloured card without heraldic hatching style from plain text.
