Planet Earths naturally occurring pink lake - Lac Rose, Hmmm, for girls only?
Actually in 1914 pink was one considered to be a masculine color whereas powder blue a feminine one.

However, let's talk about the original topic at hand: Lake Retba or Lac Rose which is strawberry pink in color but not as a result of industrial pollution but rather harmless bacteria called Halophile bacteria. These bacteria live in extreme environment and actually thrive.
From the website Amusing Planet:
"The strawberry colour is produced by salt-loving organism Dunaliella salina. They produce a red pigment that absorbs and uses the energy of sunlight to create more energy, turning the water pink," said Michael Danson, an expert in bacteria from Britain's Bath University.
Covering an area of about 3 sq km, the lake is located about 35km north-east of Senegal’s capital Dakar. Since the 1970s, local residents have been mining Lake Retba for its salt, which they use mainly to preserve fish. [Link]
