Synopsis:
When Barry Allen learns that Mirror Master is on the loose again, he releases his costume from his ring in order to become the Flash. An explosion then occurs which causes his vision to change. Everything he sees is now green in color. Despite this handicap, Flash still manages to capture the Mirror Master.

Barry and Iris then attend a Colorama show held by color expert Dr. Maybrook. During the show Barry can perceive color again. He attempts to question Maybrook after the show, but is asked to leave. While he waits for another chance to talk to Maybrook, Barry learns that several audience members were robbed during the show. He returns to find Maybrook injured.

Barry learns that an engineer had utilized Maybrook's technology to hypnotize audience members. He then robbed them during the show. Barry tracks down Baker, the engineer, and apprehends him. He then visits Maybrook in the hospital. He discovers that radiation from one of the artist's color technology test interacted with the chemicals in his ring and caused his color vision problem. With Maybrook's help, Barry's vision is restored.
