What describes an image that creates a deceptive visual effect?

The term that describes an image creating a deceptive visual effect is "illusion." This concept refers to a perception that differs from reality, often resulting from the manipulation of visual elements or the juxtaposition of certain patterns, colors, or shapes. Illusions can trick the brain into seeing something that isn't there or interpreting a scene in a way that is contrary to physical reality.

In the context of visual art or design, illusions are often used to create interesting and engaging experiences for viewers, challenging their perceptions and encouraging deeper observation. Other terms like "shade," "hue," and "style" relate to color theory and artistic expression but do not specifically address the aspect of deception in visual perception. Shade refers to the darkness of a color, hue defines the color itself, and style refers to the distinctive manner of expression in design or art, none of which relate to the concept of creating a misleading visual effect.
