Composition en rouge, jaune et bleu Composition in Red, Yellow and Blue

At the beginning of the 1920’s, Mondrian began to put his ideas on a new architecture into practice. He painted the walls of his studio white and the floor black, hung colored boxes on the white walls and combined them in different configurations. In doing so he tested the effects of colored fields in his paintings structured with black lines crossing at right angles. The both monumental and harmonic effect of his paintings varied depending on the size and position of the colored field. In talking with artists and architects, Mondrian became convinced that Neo-Plasticism – as this new form was called - would first be fulfilled in architecture.
