How Australia’s Lake Hillier gets its pink color

Lake Hillier in the Recherche Archipelago of Western Australia is known for its pink color.

The lake’s bubble-gum color continues to be debated but scientists indicate that the pink body of water is the result of the intermixing of Halobacteria and a salt-tolerant algae species called Dunaliella Salina.

The Halobacteria is known to produce red pigments which when mixed with salt-tolerant Dunaliella Salina, creates a stunning strawberry milkshake color.
