Three lakes, changing coloursSourced
The crater lakes change independently
Kelimutu in Indonesia has three crater lakes of differing colours. Their colours can change with volcanic gases and the chemical conditions of the water. The changes are independent because each lake has its own connection to the volcanic system below.
A fixed colour chart cannot describe the lakes forever.
