This paper examines Ad Reinhardt's black painting from the perspective of the art education advocated by the artist's own [How to look]. His ideology regards visual experience as a process of entanglement between humans and material, as well as a process of realization of the spirit. Art appreciation is a process of experiencing material and the experience as a producer must be shared so that people can be reborn as an independent producer. Black painting emphasizes the materiality of the work by eliminating elements of representation and expression and thoroughly denying meaning. People come to pay attention to the production method of black painting as they experience material reality in an aesthetic environment that allows them to be faithful to their sense of sight. People see the material reality directly, trace the artist's thoughts from its production method, and share their experiences as producers. Black painting encourages people to express themselves while helping them to know what they are looking at. Therefore, the visual void of black painting is a blank space for people, a space that each individual fills as a creative producer.
