ELSPA (Entertainment and Leisure Software Publishers Association) Has announced a new ratting system in the UK that will use colors to tag different video games with different ratings. I hear a similar technique is used in food packaging. I have not found out what colors mean what, but I am assuming that red will be bad, all the way to green for good, and what ever colors might be in-between.

UPDATE: I have found the colors and the ratings they represent.
