Gradient by Adam Dadswell

Effect

Gradient is a mentalism prop that uses color swatch cards resembling real paint samples. The audience sees a set of ordinary-looking color cards, each with unique names like "Purple Rain" or "Ocean Teal." The performer can predict a chosen color, reveal hidden thoughts tied to emotions, or make impossible matches—all while the cards remain examinable. The effects feel organic, as if the performer is simply interpreting colors rather than performing a trick.

Full details

Gradient consists of 20 bridge-sized color cards, two reference cards, and a storage box. The cards are marked, allowing the performer to identify them easily, and they follow a memorized stack for advanced routines. The set includes over 1.5 hours of video instruction, teaching multiple effects:

• Gemini Tones – A color-based twist on the Gemini Twins principle, where two selections match a prediction.
• Emulsion – A psychological routine where emotions are linked to colors, inspired by Dai Vernon’s Emotional Reaction.
• Influence of Color – A deceptive color-matching effect where the spectator’s actions unknowingly arrange the cards perfectly.
• Mental Match – A compact version of classic color-matching mentalism.

The cards are made of standard card stock, so they require careful handling to avoid wear.

Who should consider the trick

Gradient is ideal for mentalists and magicians who want a non-card-based prop that still offers the versatility of a marked deck. It works well for close-up, walk-around, or table-hopping performances. Those who enjoy psychological routines, color-based magic, or interactive mentalism will find it especially useful.

Information on how difficult it is to perform

The difficulty level is moderate. Reading the markings is straightforward, but memorizing the stack requires some effort—though Adam Dadswell provides mnemonic techniques to help. The taught routines are mostly self-working or rely on simple sleight-of-hand techniques. Performers comfortable with basic mentalism principles will adapt quickly.

What magicians say

• Mentalist on a Shoestring praised Gradient’s natural appearance, saying, "Adam has done bloody good on these... they look like something you’d pick up in a real-world setting." He also highlighted the bonus content with Lewis Le Val as a valuable addition.
• Chris Edwards Magic called it "a nice alternative to playing cards," emphasizing its practicality for walk-around performances. He noted that while the card stock isn’t waterproof, the marking system is "super easy to read without being obvious."

Both reviewers agreed that Gradient offers strong, versatile routines while maintaining a deceptive, everyday appearance.
