Chroma expands upon Alyson Shotz's ongoing interest in the perception and sensation of color. The sculpture, a half sphere laminated inside with thin strips of clear acrylic and dichroic film, appears to be full of color that shifts as the viewer moves. However, there is no intrinsic color to any of the material. Instead it is the physical properties of the metallic oxides in the dichroic film that cause different wavelengths of light to either reflect or transmit some wavelengths more than others. This causes the color of the sculpture to change depending upon the viewer's spatial relationship to it, in addition to the added variables of angle and intensity of incident light. In collaboration with environmental and viewer interaction, Chroma is a vehicle for the experience of pure color.
Alyson Shotz has a current solo exhibition at the Edythe and Eli Broad Museum, East Lansing, MI. Recent solo exhibitions include The Indianapolis Museum of Art, Indianapolis, IN; The Phillips Collection, Washington, D.C.; Espace Louis Vuitton, Tokyo, Japan; and the Borås Konstmuseum, Borås, Sweden. Her work is included in the permanent collections of the Solomon R. Guggenheim Museum, New York, Hirshhorn Museum and Sculpture Garden, Washington D.C., San Francisco Museum of Modern Art, and Whitney Museum of American Art, New York among others.
