An expressionist painter is an artist who uses bold colors, exaggerated shapes and distorted forms to convey emotions and inner feelings through their artwork. Expressionism is a style that emerged in the early 20th century as a reaction against traditional forms of art, with artists aiming to break away from realistic representations and instead focus on conveying subjective experiences and emotions. In expressionist paintings, color and form are used symbolically to evoke feelings and moods, often depicting scenes that are dreamlike or nightmarish in nature.
