In 1919 Van Doesburg devised a so-called ‘colour solution’ for the house of Bart de Ligt with blue, green, and red planes on the walls and ceiling. Naturally, these colours could not be seen in the black and white photograph in De Stijl magazine. Van Doesburg used this photograph six years later for publication in L’architecture vivante. Now he made the planes in red, yellow, and blue. In the meantime, this had become De Stijl’s characteristic colour scheme.
