Walking by the salt ponds in late afternoon, I took this photo of blue waters, crystallizing salt and packed salt beds beyond.
After a few days, note the red pinkish hue of the water. In researching the reason for this coloration, I found this is due to the presence in the salt pond of "halophilic archeabacteria" bearing carotenoid compounds. These microorganisms thrive in areas of high salinity.
Live and learn!
