The red letters bar us from entering. Entering what? A space that is on the other side of the surface of the picture, behind the picture, so to speak. However, by indicating the boundary that we are not allowed to cross, this text, also automatically demonstrates the limits of its own possibilities. The surface of the picture is , after all, also the limits of its own power. The space on this side of the boundary does not belong to it. That is to say, the surface functions as boundary of the social space here.
As far as the victory of red over blue is concerned, this should apparently not be considered unconditional. After all, the letters “DA” (“YES”) stand in the centre of the red line – precisely where the perspective lines of the blue letters meet behind them, the point of their maximum depth. In addition, the “DA-NET” (“YES-NO”) combination gives the prohibition a certain contradictoriness, casts doubt on it», - Erik Bulatov: “Freedom is Freedom”, Kerber Verlag, 2007.
