From The colour circle series, part 1.
The colour circle series consists of nine colour circles, each made up of 24 equidistant hues.
The circles are subdivided into three categories: part 1, part 2, and part 3, each consisting of three works.
The constant colour circle is a colour wheel based on the three primary colours: red, blue and yellow, which are mixed to create a total of 21 interstitial colours. These pigments reflect Eliasson's choice of gradient hues between the primary colours.
The constant colour circle functions as a base for the colour mixtures in all the other circles in The colour circle series.
