ROY G BIV series
It may not be a double rainbow, but this series of diptychs is still pretty bright and vivid. What does this mean? Well ROY G BIV is the acronym for the colors of the electromagnetic spectrum and these 144 diptychs were pulled for their colorful qualities. There's even a key to help you identify where each diptych was taken, though maybe you’ll recognize a few on your own.
