#523 - Triangle Labels

Since 2001, all Nintendo games released in Europe have a coloured triangle label on the side of their boxes. The colour of this label refers to the languages of the game and the country where it's distributed. For example: red is France, pink is Spain... There are 49 possible colours for this label, the most common one being yellow (distributed all across Europe and in all available languages).
