Enthralled by the various purple hues of San Francisco Bay salt ponds, California-based Julieanne Kost decided to capture their beauty in a series of photographs while flying past them.
The colors are naturally occurring, caused by the salinity levels of the salt ponds and the micro organisms thriving in them. You can learn more about this phenomenon here.
