In informal art, which focuses on the inner world and the senses of the artist rather than the external world, the artists produced individual and original works with formal and technical freedoms. In France and Europe, after World War II, parallel to American Abstract Expressionism, Informal Art works contain all kinds of experience of line, stain and color. In abstract compositions, the concepts of picture balances, unity-integrity and contrast are taken into consideration. Leading artists include Jean Fautrier, Georges Mathieu, Pierre Soulages, Hans Hartung and Wols. In informal art, psychology and the subconscious have an important place in the artist's structuring of his work. In the creative process; for artists who produce through spiritual improvisation, the concepts of randomness and dynamism and transformations have an important structure. In most works, with the release of consciousness, we encounter large surface stains, abstract compositions, dripping and splashing. Through this inner journey, where the elements of painting, surface formations and materials are diversified, we can observe personal artist experiences. In this research, it was observed that informal artists have achieved their own subjectivity, their own forms and their own self-forms by means of different materials to reach specific aesthetic values. With the aesthetic sensation and meaning of the processes, the formal surfaces that are kneaded with pure emotion as a result of momentary and random orientations reach a certain level of expression with space and quantitative interpretations.
