Since 2009, Olafur Eliasson has been engaged in a project involving a new color theory based on the prismatic colors and explored through a series of painted artworks. He began these experiments by working with a color chemist to mix in paint an exact color for each nanometre of light in the visible spectrum, which ranges in frequency from approximately 390 to 700 nanometers. Since the initial experiments, Eliasson has used this palette to make paintings on circular canvases, known collectively as the Colour experiment paintings. Using this system, Eliasson has also created compositions that range from simple explorations of the spectrum to more complex efforts to capture the color in a specific source image. They are comprised of multiple layers of very thinly applied paint to create a seamless transition between colors. In Colour experiment no. 119 (Hekla), Eliasson captures and interprets the intersection of color and light within a specific photograph of the Icelandic volcano bearing that name.
Using this largely grayscale color gradient as the background, Eliasson then places a piece of Icelandic sea ice, harvested from waters near his Reykjavik studio, at the center of the canvas, in an intentional gesture of experimentation. As the ice melts, the artist adds small quantities of pure pigment, which are carried across the canvas to create a new landscape of color fields. Formless blue and gray explosions spreads out from the center of the canvas, contrasting starkly with the even background. Metaphorically, the dematerialization of the ice, and its interaction with the color pigments illustrate the infinitely transitory nature of natural phenomena, as well as both the beauty and fragility of the landscape.
