Four Colors is a real time generative visual performance based on the concept of how a self-imposed technical limitation can nevertheless lead to the creation of a very rich visual output. In this case, the limitation consists in using only four solid colors as the starting point of the performance; then different audio signals and their magnitude will be used to define how these colors interact with each other and with sound itself, generating potentially infinite patterns and abstract landscapes. This performance was premiered in Berlin on October 19 2017 during a live show with Eexxppoann.
