To have the colour of the Coca-Cola logo in a different colour to anywhere else (in this instance, it's black and white, rather than red and white). PS - This may also be (unofficially) the only place in the world where the Coca-Cola logo advertised (the official one) is not red and white.
How the hell could you possibly know that? Well done though. They WON'T advertise Coca-Cola unless it's in colours other than red and white, because River Plate play in red and white and they don't want the colours associated with the club. Nar then...
I know what you mean mate. Those coloured badge thingeys that the clubs have in the programme and what not. No, I'm talking about an actual coca-cola advertisement. Not a gimmick to do with the club but an actual advertisement. They've actually (officially) changed the logo to black and white, because they wouldn't allow coca-cola to daub La Bombonera in red and white. If you go to the ground or see pictures - there is NO red and white colour anywhere near it.
Look at this picture at the advertising boards near the bottom of the stand and their is a coca-cola red and white one. http://cultureofsoccer.com/wp-content/uploads/2007/05/boca_fans.jpg
was a big red and black coca cola logo across the front of the ponty end a couple of years ago Several big yellow and green ones at norwich and not a red and white one in sight.
