The 'shadowfield' is illuminated by rows of LED lights arranged in alternating bands of red, green and blue. The abilitiy to change the combinations of primary colours renders the work with an infinite number of compositions. These shifts in the colour combinations intensifies the perceptual experience through the play of apparent colour and manifestation of scintillating after images. The combination of these primaries colours with the fins and shades of the structure set up a dynamic confluence of complimentary shadows and secondary light affects. As one approaches the work the complexity of colour mixing becomes apparent as seemingly solid bands of coloured light show themselves to be made up of a spectrum of mixed hues.
