Color

line

Answer 1

The element of art used to create the illusion of depth in a two-dimensional work is color. Artists often use techniques such as atmospheric perspective, where colors become lighter and less saturated with distance, to create the perception of depth. While other elements like line and form can also contribute to the sense of depth, color plays a significant role in how we perceive space in artwork.
