What can change the appearance of an artwork?

The appearance of an artwork can be changed by various factors, including lighting, framing, and the medium used. Different light conditions can alter colors and textures, while framing can influence how the piece is perceived in context. Additionally, changes in the medium or technique, such as using different materials or styles, can completely transform the visual impact of the artwork. Lastly, viewer interpretation and cultural context also play significant roles in how an artwork is perceived.
