Ishihara Test by Liam Levanon

Liam Levanon's 'Ishihara Test' is a clever psychological magic routine that plays on perception and memory using the well-known color blindness test. The performance begins with a seemingly genuine assessment of the spectator's color vision, but the real magic lies in the unexpected twist—revealing that the spectator misremembered the card backs as gray when they were actually multicolored. This routine leverages selective attention and inattentional blindness, creating a strong 'aha!' moment. Perfect for close-up settings, the trick is easy to perform but delivers a powerful impact, making it a fantastic addition to any magician's repertoire.
