Unconscious Colour

Interactive Projection


Using a computational spectrometer, colors in the light were measured in the caves and then represented graphically in 3D. The interactive display increases in color as more audience members approach the screen.

Project Description

When there is no light there is no color, so while doing light studies in the caves, the spectrum data was often affected by the presence of the portable lights we brought with us: by entering the caves, we were also bringing color. The idea of us transporting an invisible spectrum made me think about how it is possible to affect an environment unknowingly. Pollution and man-made influence can be nearly undetectable, even artificial lighting has its environmental impact.
