Ross Manning is an emerging artist who works with the most basic elements of some of the most sophisticated technology today. His Spectra series is an ongoing project exploring the aesthetic potential of the additive colour model. Additive colour mixing, and specifically the RGB (red, green, blue) colour model, is at the centre of digital image reproduction, employed in all camera, screen and projection based technologies, as well as film-based colour photography. When coloured light beams, or spectra, of different wavelengths are overlayed, the cumulative wavelength produces a new colour.
