The theoretical approach to the topic of this research includes defining and explaining basic concepts such as colour, contrast, texture, colour mixing and other, which are important for the further course of the research. Through the historical overview of the events that led to the development of pointillism in the 19th century and then abstract expressionism in the 1940s, we determine the circumstances in which they occur and get to know their most important representatives. Pointillism, with its representatives Paul Signac and Georges Seurat, brings us a very demanding and refined way of painting, which is characterized by many small "dots" that when viewed from a distance, merge in the human eye and create the illusion of a certain colour. This phenomenon is called optical colour mixing. Jackson Pollock, on the other hand, brings to the world of art spontaneous and energetic abstract expressionism, also known as action painting. From the very name of this direction, we can assume that it is an action in which the artist paints from all sides of the canvas, he is in motion, he uses different ways of applying paint to the canvas and thus expresses his energy. The mentioned two artistic directions in their definition have concepts that appear through the teaching of Art Culture and can serve as an inspiration for pupils to express themselves in art work. In the practical part of the research, the process of painting art works is presented, which can serve as an example of the way in which pointillism and abstract expressionism could be included in the teaching of Art Culture.
