Looking into the unpainted lateral surfaces causes a transition of perception from the "frontality" of the colour to the depth effect of the object, which lends plasticity to the colour without repudiating its binding link with the surface and makes it to seem to hover. Released from the wall, colour develops a power that allows it to radiate into space. Even when it still adheres to the orthogonal frame of reference – which it does not always do since it is essentially unstable – its new effective dimension is tangible. It categorically eschews unambiguity. It differs from American "Shaped Canvas" painting in being bound into a system.
