All Colours White

All Colours White casts a continuously evolving colour spectrum onto a concrete wall. As red, green, and blue light created by three light-emitting diodes (LEDs) shine through rotating shutter blades, the beams of light are sliced into overlapping bands in an endless loop of shifting hues. When the blades align vertically and the light cones overlap for a brief moment, a band of pure white light emerges, only to dissolve in an instant as the blades rotate further. The interference patterns created by the blades disguise the constant output of the LEDs, revealing the phenomenon of colour as a product of the interaction between the eye, the mind, and the wavelengths of the electromagnetic spectrum that are visible to the human senses. The work crystallises the distinction between human, mechanical, and perhaps other-than-human sensing, which might perceive a different array of colours.
