For the first time, field hockey is being played on shocking blue turf at the London games.

Designers behind the idea claim the game is somehow faster on blue, made famous stateside by Boise State's football team.

Australian and South African men who played on it Monday morning say they only notice a difference when watching on TV.

The switch from green is going to take some getting used to for spectators at Riverbank Arena.

Imagine watching Michael Phelps plunge into a purple pool or LeBron James dribble on a green court.

Even more eye-opening to some was the hot pink border to the field. "It's a little bit extreme," says Andy Sugden, a Londoner.
