Window 111×90 cm 1912~1913 Centre Pompidou, Musée National d'Art Moderne Collection

Delaunay (R. Delaunay 1885–1941) was a French painter and one of the founders of 20th-century abstract painting. His abstraction was liberated from Cubism, taking color as its essence and developing a rhythmic organization of color planes. The poet Apollinaire called it Orphism. He was one of the earliest non-representational painters.

The theme of the window here becomes a kind of recollection. Opening the window, light becomes dazzling and vivid color planes (red, green, pink, blue, black...). Color becomes the concrete form and subject of this painting. Delaunay wrote: "Around 1912 to 1913, I had a conception of painting that depended on the technique of color contrasts. I used the scientific terminology of the scientist Chevreul: 'simultaneous contrast,' flexibly deploying color, just as we can express a fugue through color sentences like music."
