CONCLUSION
The current attempts by artists and psychologists to discover formal correspondence schemes of chromaethesia have a long history of experiments in art and science, and it may be concluded that the phenomenon of chromaesthesia is difficult to control or manipulate. Artistic experiments, have uncovered interesting dynamic and emotional aspects of chromaethetic perceptions and contributed to the phenomenology of chromaethesia.
Current psychological studies into chromaethesia have catched up with the booming brain research and are mainly involved in a search for organic substrates. Current artistic experimentation seems mostly involved with digital devices and a search for algorythms to translate music into images (e.g. visual music, animation). The present situation in artistic chromaethesia research may be compared to the late nineteenth-century period of experimentation with color-organ technology. After that an era followed of fruitful artistic explorations and scientific testing of the psychological (perceptual and emotional) impact of sound-image devices and performances.
