One possible solution to this is to have numbers superimposed on the balls for TV/computer viewers so the announcers and viewers are on the same page. This wouldn't be rocket science. The players certainly don't need the numbers or solid/stripe denotations on the balls to play.
I fail to see how numbers on a red/yellow set would be any more visible or distinguishable than the standard solid/stripe. We would be twisting our heads around to see the numbers doing a dance in our computer chairs to figure it out half the time.
I say superimpose the numbers on the balls, it won't matter what numbers are assigned to each set so long as the announcers and viewers are on the same page, the players could remain completely oblivious to this and it would not change the outcome of play.
