Story highlights Algae to blame for green hue of Olympic diving pool

Water was blue on Monday, but green on Tuesday

(CNN) During the opening ceremony, the Rio Olympics organizers talked about a green environment.

They were not talking about the pools at the Maria Lenk Aquatics Centre.

But on Tuesday, the water in the pool where the divers for the women's synchronized 10-meter platform competed -- officially called a diving well -- was dark green.

The green hue seen in the water was due to a proliferation of algae caused by the heat and lack of wind in the venue, said the Rio 2016 Local Organizing Committee.

In a statement released to the media, the committee stressed that the water was tested and there was no risk to athletes. It also said the diving well should be back to its normal color for the events on Wednesday.
