Between 1950 and 1958 Francis spent time and painted in Paris, the south of France, Tokyo, Mexico City, Bern and New York. His artistic development was affected by his exposure to French modern painting, Asian culture and Zen Buddhism in particular. His paintings of the 1950s evolved through a series of stages, beginning with monochromatic abstractions, followed by larger richly colored murals and "open" paintings that feature large areas of whiteness. After his 1953 painting "Big Red" was included in the 1956 exhibition "Twelve Artists" at the Museum of Modern Art, New York, Francis began a rapid rise to international prominence.Francis painted large murals for the Kunsthalle, Basel in 1956-8 and for the Chase Manhattan Bank, New York in 1959.Between 1960 and 1963 he created several series of works, including the "Blue Balls" series. Consisting of biomorphic predominantly blue forms and drips, these works referenced the pain that resulted from the renal tuberculosis that he suffered in 1961.
