Abstract painting is a style of art that does not attempt to represent an accurate depiction of visual reality. Instead, it focuses on the use of color, shape, form, and gestural marks to create a composition that is non-representational and often non-objective.

This style of painting emerged in the early 20th century and has since become a significant and influential movement in the art world. **
