The colors on display, originate from an algorithmic formula that starts from the colors of the facade of the Dan Panorama Hotel in Tel Aviv (architecture of the Seventies). They start from primary red and progress through orange, yellow, green and cyan to primary blue.The printed colors, isolated on glossy rectangular photographic papers are not the real reproductions of the original colors. They are, instead, the translation of the logic applied by the author on gradational transition from one color to another. This is how a reproduction can result in isolating the logic of color applied to architecture.
