I support a system where the fans decide the winner as they are clearly the most objective.

I suppose you would use some sort of applause sytem like:

"Give it up for greeeeeeen!" and then a meter measures the decibel level. Then repeat for red.

Or I suppose the fans could text "GREEN" or "RED" to 90210 and at the end of the day, the winners could be announced just like on American Idol.

The only other possible solution I can see is having the referees explain every rule to each fan and make sure they are all on the same page before the event. That way the fans are not in the dark as to the rules. I suppose we will have to start certifying fans. If they don't pass a rules test with at least a 90, they will not be able to be fans anymore or something like that. I'm still hammering out the details.
