Electricity opened new possibilities for projected light, which were exploited by the British painter A. Wallace Rimington, whose Colour Organ formed the basis of the moving lights that accompanied the 1915 New York premiere of Scriabin's synaesthetic symphony Prometheus: A Poem of Fire, which had indications of precise colors in the score. Scriabin wanted everyone in the audience to wear white clothes so that the projected colors would be reflected on their bodies and thus possess the whole room.
A similar demand for white-clad audience was posited by the Italian Futurist artists Arnaldo Ginna and Bruno Corra, who experimented with "color organ" projection in 1909 and painted some nine abstract films directly on film-stock in 1911. The German Hans Stoltenberg also experimented with drawing abstractions on film about this same time, and the Finnish/Danish/Russian Leopold Survage (then resident in Paris, and friends with Picasso and Modigliani) prepared hundreds of sequential paintings for an abstract film Rythme Coloré, which he hoped to film in one of the new multicolor processes that were being developed, but the onset of World War I prevented that; he sold a number of the paintings, so that they were widely dispersed and have still not been filmed

The clearest clue is provided in a manifesto on "The Painting of Sounds, Noises and Smells", by his comrade Carlo Carrà: - "...rrrrrrreds that shouuuuuuut, greeeeeeeeeeeens that screeeeeeam, yellows, as violent as can be.
