Simply known as Blue Lake , the beautiful artificial lake that changes the colors

Simply known as Blue Lake , the beautiful artificial lake located in Japan each autumn changes color in the eyes of observers .

From October to November this year, the lake changes its color from crystal blue to emerald green .
Changing the clean and strong colors never fully explained , so that the theories range from the color depends on the ingredients in water until weather conditions .

In any case , the view is amazing beautiful , so maybe that's why no one has asked the most logical explanation .

Enjoy vibrant , magical nature:
