Because of her service in Occupied Japan, Lillian was subjected to two years of intense ionizing radiation. Her thyroid developed a tumor and was removed. In 1950, she developed chorioretinitis, an eye disease that impacted on how she viewed colors. She discussed the psychology of sight, perception, and dimension with Bela Julecz and Leon Harmon of the Labs, and Edwin Land of Polaroid. Edwin showed her a wheel of black lines with white separations. Twirling the wheel eventually created faux color. ENIGMA did not follow Land's twirling but used special editing techniques and texturing of black and white lines; the pounding music and the overwhelming bombardment of blacks and whites changed the eyes' interpretation of vision; everything became saturated colors.
