During the 1950s and 60s, partly due to the advent of quick-drying acrylic paints, artists developed a new style of painting called ‘hard-edge geometric abstraction’. Many painters took an interest in spatial illusion, retinal stimulation, and psychedelic visual language. A number of Tanabe’s works from the 1960s and early 1970s incorporate vibrant colours and geometric shapes, formulating a dialogue on the visual features and parameters of landscape.
