Humans constantly apply a bilateral system of colour interpretation: that of light and pigment. The objective of these experiments / installations was to verify White’s illusion (White 1979) in a comparison between three natural liquid colour contrasts and three basic colour food colouring in water contrasts. The illusion involves changes in the lightness of a colour test element that interrupts a dark or a light- bar of a dark-light square wave grating (White 2009). In Experiment 1 we used three different basic colours of food colouring in water compared with Experiment 2, where we used natural food liquids. We proposed a three dimensional structure, composed of glass jars containing the coloured liquids. The transparency of the container allows for a complex pigment light interaction. Typically illusion experiments have been visualized with pigments on paper. The use of coloured liquids in a three dimensional structure created the same effect as the Munker White illusion; lightness or colour assimilation occurred in these multidimensional versions.

Abstract
Humans constantly apply a bilateral system of colour interpretation: that of light and pigment. The objective of these experiments / installations was to verify White’s illusion (White 1979) in a comparison between three natural liquid colour contrasts and three basic colour food colouring in water contrasts. The illusion involves changes in the lightness of a colour test element that interrupts a dark or a light- bar of a dark-light square wave grating (White 2009). In Experiment 1 we used three different basic colours of food colouring in water compared with Experiment 2, where we used natural food liquids. We proposed a three dimensional structure, composed of glass jars containing the coloured liquids. The transparency of the container allows for a complex pigment light interaction. Typically illusion experiments have been visualized with pigments on paper. The use of coloured liquids in a three dimensional structure created the same effect as the Munker White illusion; lightness or colour assimilation occurred in these multidimensional versions.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
