Ishihara Test - Liam Levanon

"Clever quick trick to carry in your wallet. It has a unique and well motivated plot that's guaranteed to get a scream!" - Oz Pearlman

"Liam showed me that trick the first time we met at the Ruskin in Blackpool in 2022. I LOVED IT and urged him to release it! Unlike most color changing card effects, It has an emotional hook and is so logical. I will be carrying this one in my pockets right now and will probably use it right after Color Monte (yup, it's that good!)" - Michel Huot

"This is more than an effect - it's a conversation piece with a great hook. The punch is so strong because they never see it coming..." - Lior Manor

The standard color blind test becomes a surprisingly colorful effect. Liam Levanon has taken a piece of science and used it as an engaging presentation for a color change effect that catches every audience by surprise. See the world in a new color when you perform Ishihara Test.

Here’s what happens:

You introduce a small packet of grey-backed cards with odd green and red dots in patterns that form numbers. You explain that this is the standard test to check people for red/green color blindness. If they can see the numbers in the patterns made up of the dots, then they are not color blind. On the other hand, if they can’t see the numbers, they should have their eyes checked. Upon confirming that everyone sees the numbers, you make a magical gesture and change the way your audience perceives colors. When you display the cards again, the audience is momentarily confused because everything looks the same. That’s when you turn the cards over, and the grey backs have transformed into a rainbow of colors. The cards can then be handed out for immediate examination.

Ishihara Test is instantly engaging to any audience because it’s based on the actual color blindness test. Liam Levanon shares with you extremely simple sleight of hand that makes this effect convincing and surprising. The custom-printed cards do almost all of the work for you. There are no flaps or sliding panels, and the vivid colors almost pop off the cards themselves. This one is perfect to carry in your wallet for when you need a spur-of-the-moment miracle. Get ready to test their vision, and their reality, when you perform Liam Levanon’s Ishihara Test.
