Abstract. ColourVision is an interactive installation that empowers people to step into an intensive dialogue with colors. Physical seating postures such as active, relaxed or reflective positions are captured, translated and trigger a rapid change of the room’s color. The installation was planned and executed for the Museum of Perception in Upper Austria, where we wanted to create seamless communication between the visitor and the color that would lead to an aesthetic experience in the space and let people experience the psychological effects of different colors
