Ishihara Test by Liam Levanon

Effect

The Ishihara Test by Liam Levanon is a packet trick that plays on the classic color-blindness test. The performer presents a series of cards with colored dot patterns, asking the spectator to identify hidden numbers. The spectator successfully names the numbers, confirming they have normal color vision. The surprise comes when the performer reveals the backs of the cards—initially appearing gray—are suddenly multicolored. The twist shifts focus from color vision to memory, creating a strong "aha" moment.

Full details

The trick uses five well-made cards resembling Bicycle quality. The routine begins with a genuine-looking color-blindness test, leveraging the familiar Ishihara plates. After the spectator identifies the numbers, the performer reveals the real test was about the card backs, which the spectator confidently recalls as gray but are now vividly colored. The method is simple, with the biggest challenge being card orientation. The trick has an instant reset, making it practical for repeated performances.
