what is silhouettes
A silhouette is the image of a person, animal, object or scene represented as a solid shape of a single color, usually black, with its edges matching the outline of the subject. The interior of a silhouette is featureless, and the whole is typically presented on a light background, usually white, or none at all. The silhouette differs from an outline, which depicts the edge of an object in a linear form, while a silhouette appears as a solid shape.
