Spectral Evidence is a moving image work about colour perception and colour language. Combining research into the evolution of the eye, the physics of light, linguistics and semiotics the work takes colour as a case study to investigate the cultural and biological limitations on human meaning making in our encounter with the world.

Displayed across two screens, the first is arranged sequentially based on the order of the colour spectrum as identified by Isaac Newton in 1665. The second follows the sequence of acquisition of colour terminology suggested by Berlin and Kay in their publication 'Basic Colour Terms' from 1969.
