About This Puzzle
Did you know? The shifting blue-purple sheen along these curled edges echoes iridescence, the optical effect in which a surface appears to change color as the viewing angle shifts, caused by wave interference of light in microstructures or thin films. The word itself comes from the Greek "iris," meaning rainbow. Source
