A silhouette is a dark shape or outline of an object that is visible against a lighter background. It is often created when a light source shines behind the object, causing the details to fade and leaving only the outline. Silhouettes can be seen in various forms of art, photography, and design, where they emphasize the shape rather than the details of the subject. Silhouettes are commonly used in graphic design and illustration to create striking visuals. They can represent people, animals, or objects, and are often employed in posters, logos, and animations to convey a message or theme effectively.
