What does colage mean in art?

Collage is an artistic technique that involves assembling various materials, such as paper, photographs, fabric, and other objects, onto a surface to create a new cohesive artwork. This method allows artists to combine different textures, colors, and forms, often challenging traditional notions of composition and representation. Originating in the early 20th century, collage has been used by many artists to express complex ideas and emotions, making it a versatile and innovative form of artistic expression.
