Physichromie is an art movement that emerged in the mid-20th century, primarily associated with the works of Venezuelan artist Carlos Cruz-Diez. It focuses on the interaction of color and light, emphasizing how colors can change based on the viewer's perspective and the surrounding environment. The technique involves the use of colored filters and transparent materials to create dynamic visual experiences. As viewers move around a Physichromie artwork, they may perceive different colors and patterns, highlighting the idea that color is not fixed but rather a fluid experience shaped by context and perception.
