Water color has a murky explanation

Green, not gold, was the color of the day at the Olympic diving venue.

Sure, China won its third consecutive gold medal on Tuesday, but the buzz was about the color of the water in the diving pool - a murky green.

That was in stark contrast to the pool's light blue color the previous day and also that of the clear water in the second pool used for the water polo competition at Maria Lenk Aquatic Center.
