In this work we establish an all-visible, all-photon, path-independent orthogonal photoswitching system enabling to enrich each of the four possible states with very high yields (Figure ). To this end we use a combination of two indigoid photoswitch types disseminated only recently by our group, a rhodanine derivative 1 and perianthracenethioindigo (PAT) 2. The resulting four switching states of 1 and 2 are significantly distinct in their spectral signatures and resulting color, which established a four-state photochromic behavior. When transferring the color changes into a transparent polymer material, multi-photochromic properties could be controlled with temporal and spatial resolution, showing direct applicability for erasable displays, optical memories, or reconfigurable optical filters. Another field of application is represented by molecular logic operations, which are demonstrated here in an all photonic fashion with the orthogonal photoswitching system. They include different binary gates and encoders and could also be transferred to a polymeric material in a localized fashion. Additionally, a fluorescent BODIPY dye could be implemented as a third photonic component and molecular logic operations was thus elevated to include an emission output signal. First, different wavelengths of irradiation were tested for a 1:1 mixture of 1 and 2 in THF/CS2
