They were produced in collaboration with the architect and colour expert Marlu Müller-Ortloff, who in 2018 took samples from the Liebling House and prepared a comprehensive colour study. One of the carpets holds the colours that were established as the original wall paint from 1937 in the main living room in the Max Liebling house in the White City Centre of Tel Aviv. The other carpet holds the colours of a cross-section of one of the exterior walls on the outside of the same apartment that show the various paints in which the façade of the building has been covered since 1937.
