Composition II in Red, Blue and Yellow is an oil painting on canvas. Abstract composition, it consists of several rectangles separated by horizontal and vertical black lines. Two-thirds of the painting, at the top right, is occupied by a red square. The lower left corner contains a blue rectangle, the lower right corner a yellow rectangle. The other rectangles are white.
The technique used is quite complex: Piet Mondrian sketched the work in charcoal, then glued pieces of wallpaper, added strips of tape, paint and a little more charcoal, then he replaced all the elements with paint.
