What is the difference between lakes coloured blue eg Lake Cawndilla and lakes coloured pink eg
Lake Menindee (both in
Kinchega National Park)?

Pink lakes have a bug called Dunaliella Salina growing in the salt that produces Beta Carotene which is the colorant in carrots, and (artificially) in margarine.
