Colour mirror wheel continues Eliasson’s exploration of the visual ambiguity between an ellipse viewed head on and a circle viewed from an oblique angle. This work, made from hand-blown glass mirrors, suggests a three-dimensional ring made of discs whose colours progress, like those of a rainbow, through the spectrum of visible light. The effect produced by overlaid layers of transparent colour is one of Eliasson’s recurring interests; the appearance of transparency in Colour mirror wheel is simulated by panes of glass with subtly different hues.
