White Does Not Exist – Synthetic colour by Flavien Théry

Created by Flavien Théry, Le blanc n’existe pas (White Does Not Exist) is an installation exploring the reverse of Newton disc, a collection of seven neighbouring colours that when spun give us a synthetic vision of colour white. In this installation Flavien uses the reverse process with Benham and Fechner disc (also know as 'top'), rotated at high speed which produces pattern induced flicker colours. When the disk is spun, arcs of pale colour are visible at different places on the disk. One possible reason people see colours may be that the colour receptors in the human eye respond at different rates to red, green, and blue. Or, more specifically, that the latencies of the centre and the surrounding mechanisms differ for the different types of colour-specific ganglion cells (wiki).

Yet these shades have no more objective existence that white light we perceive…These impressions reside within our brains , while physical reality boils down to a steady succession of flashes red, green , and blue, clearly separated in time..
