take off your old one and spray it black for the contrast - don't think I have seen that done and I think that would look awesome! 
well ive only got the sharan badge on the back, what i was thinking (would be fiddly as hell!) buy the red badge but instead of the chrome lip spray that black would as i said be a mission but think it would look pretty safe adn adds the contrast at the same time
that wouldn't be that hard, because of the lip you could
quite easily just mask up the red part, eg mark everything and then using a craft scalpel trim the tape back, and then spray the lip, at £10 a badge it could be worth a punt.
