The Pink lake Hillier in Australia.

 When you think what color a lake might be;Blue, Brown may be even Green come to your mind.But I doubt you would ever associate the color pink with of body of water.If you traveling over the western Islands of Australia this unbelievable phenomenon can be witnessed in your own eyes.

                    

The captivating lake is not trick of light, and it retains its hue when it removed..Best guess about this is; coz of the salt concentration (10 times saltier than the ocean ) it is perfect breeding for the salt loving micro Algae Dunaliella salina . these tiny organisms produce pigment compound that can absorb light like Beta Carotene. so it seems pink.
